Conceptualizing/contextualizing megasites

Studying megasites and Balkan Neolithic tells may be mapped onto the difference between the Orient Express and a commuter train from Bushey to Euston: it is hard to comprehend the vastness of the former, while not denying the intrinsic interest of the latter. It is not only the megasites that are vast—it is also their landscapes and the time-space dimensions of the CT network. The rolling forest steppe-covered loess landscapes carry on for thousands of kilometres, while, at a local level, a single Soviet-era field in central Ukraine can be larger than an entire English parish. Moreover, the CT network lasted longer and covered a wider area than any other central and eastern European network—from 5000 to 2800 bc and more than 250,000 sq. km (Monah & Monah Reference Monah, Monah, Mantu, Dumitroaia and Tsaravopoulos1997; Videiko Reference Videiko2013) (Fig. 2). By comparison, the Vădastra network in modern Romania lasted 200 years and covered 6000 sq. km, while the Veselinovo network in Bulgaria lasted 300 years and covered 60,000 sq. km (data from Chapman Reference Chapmanin prep.). Ukrainian specialists have claimed the existence of more than 60 local ‘groups’ within the Trypillia network alone (Shukurov & Videiko Reference Shukurov and Videiko2017, 3). The scale of these phenomena is not only theoretically challenging but also poses many methodological problems of how to investigate such sites/landscapes/cultural groups (Table 1).Footnote ³

The first question of scale concerns the way that clearly similar though varying material culture was replicated over such distances and reproduced over 80+ generations. We have found Lacan (Reference Lacan and Miller1988) and Žižek's (Reference Žižek2012, 86–92) concept of the ‘Big Other’ stimulating in this respect. Alongside and ‘above’ the daily household practices which characterized the habitus—what Bloch (Reference Bloch2008) has termed ‘transactional social practice’ (see below)— the Big Other played an overarching, integrative role as a virtual symbolic order (in Bloch's terms, a ‘transcendental entity’) that existed only through its subjects believing in it—something which was sufficiently general and significant to attract the support of most members of society but, at the same time, sufficiently ambiguous to allow the kinds of localized alternative interpretations (‘transactional practices’, according to Bloch) that avoid constant schismatic behaviour. These localized interpretations became materialized in three principal forms which were all central to CT cultural identity: different types of painted pottery, different kinds of figurines and houses of different shapes and sizes (Chapman & Gaydarska Reference Chapman, Gaydarska, Werra and Woźny2018) (Fig. 3). All three forms were concentrated in the domestic domain, where the mortuary domain and hoarding practices were virtually invisible.Footnote ⁴ While for typological ‘splitters’, the variability in these three forms permitted the etic differentiation of over 60 local groups, a CT person would have emically recognized a vessel as ‘theirs’ in a pottery assemblage from a settlement 800 km away from their home. Diachronic studies of CT figurine usage shows continuity in discard practices over the entire CT timespan (Gaydarska Reference Gaydarska, Kadrow and Müller2019c). The Big Other was fundamental in the growth and expansion of the CT network, transcending face-to-face contact and local social networks to enable continuities of practice and identities across vast distances. But the Big Other leads us to an important question concerning the role of imagination in the CT network.

Figure 3.

In Imagined Communities, Anderson's influential study of the anomaly of modern nationalism, the author (Reference Anderson1991, 4) reminds us that all communities larger than a single village were ‘imagined communities’, because separate communities have, by definition, never lived together with a second group. Bloch (Reference Bloch2008) has recently expanded the use of the term ‘imagined communities’ to beyond the political framework, suggesting that the transcendental social consists of essentialized groups which exist because they are ‘imagined’, whether as descent groups or religious groupings. There are therefore three different levels at which imagined communities have taken root in the CT network: at the level of the megasite, at the level of the descent group whose members spanned two or more settlements, and at the far larger scale of the ‘Big Other’ itself. The Big Other can be conceived in Bloch's terms as ‘a totalising transcendental representation without its political foundation’ (Reference Bloch2008, 2060).

For the imagined community of megasites, we suggest that the first step of the integration of people beyond their normal, face-to-face groups had been taken through the evolution of the Big Other as much as the development of transcendent local and regional descent groups. But local Trypillia settlement groups still required a vision of how diverse communities could live together to derive benefits from the new settlement form that were considered greater than the difficulties this linkage may have brought. After all, there is a long tradition, supported by Childe (Reference Childe1958), of actualizing the advantages of autarky—living in independent, face-to-face communities—which put a long-term brake on the scale of settlement nucleation in prehistoric Europe.

It is easy to forget the unprecedented nature of Trypillia megasites, which have created immense problems of explanation and understanding, but first of all, problems of imagination. On the Eurasian continent of the fifth–fourth millennia bc, the Trypillia megasites were unique in size and scale. There was nothing anywhere else on the planet, at 4200 bc, to compare with the Phase BI megasite of Vesely Kut, covering an area of 150 ha—no analogies from which to derive this extraordinary place. In our discussion of how the earliest megasites were imagined, we shall return to the issues of their cultural background, the changes which stimulated their growth and their advantages and disadvantages.

In the theoretically divided terrain of the last three decades, one of the areas in which post-processualists, interpretative archaeologists and those of the ontological turn have made least impact has been urbanism. With a handful of exceptions (e.g. Christopherson Reference Christophersen2015; M.L. Smith Reference Smith and Smith2003), research into urban developments has been the domain of the processualists, who have focused on wide-ranging processes of change and often grand narratives to account for what was clearly a critical step in the human past (Flannery & Marcus Reference Flannery and Marcus2012; Marcus & Sabloff Reference Marcus and Sabloff2008). One of the problems that interpretative archaeologists have faced is the scale of the processes, which tend to be beyond their comfort zone. As previously discussed, the similarities of the scale of CT settlement and those of early urban networks make the interpretation of CT just as problematic as other early cities. This means that conceptualizing CT in terms of the Big Other and ‘imagined communities’ does not make for ready linkages to urban origins. The route that we have taken remains, however, true to post-1980s contextual and relational approaches.

The term ‘urban’ is a modern analytical construct, largely used as an essentialist concept, but more recently used to encompass very different phenomena worldwide. This contradictory usage stems from the tension between the desirability of a single definition and the diversity of cases that make this impossible. Historical, anthropological and epigraphic sources informing us about the emic views of cities reveal not only linguistic differences but, more significantly, very different understandings of the phenomenon. Thus, the introduction of an etic category such as ‘urban’ seems reasonable to reconcile these cross-cultural differences, allowing comparisons of human development. It is easy to overlook this feature of the term ‘urban’ due to its Latin origin, its implied Eurocentrism and the unfortunate interchangeability of the terms ‘urban’ and ‘city’.

Defining ‘urban’ might be helpful in distinguishing between ‘urban’ and ‘non-urban’ lifeways, were it not for the static and descriptive aspects of any definition, especially in a constantly expanding field. By contrast, analytical constructs are more flexible and can be regularly updated. In this paper, we have chosen not to produce a definition of ‘urban’ since we believe that such an operation has, in the past, done more harm than good through the essentialization of selected criteria. Instead, we rely on ‘urban’ as an analytical construct whose constitutive points are relational rather than fixed. In this sense, the term ‘megasite’ resembles the Chinese character for ‘city’ or the Greek word ‘polis’.

Looking for cities in context rather than as examples of essentialized universalities is not a novel concept (Gaydarska Reference Gaydarska2017), but it has been continuously undermined by what has become the traditional view of urbanism. As early as his 1938 discussion of the number and density of urban communities, the prominent sociologist Louis Wirth noted: ‘But these criteria must be seen as relative to the general cultural context in which cities arise and exist and are sociologically relevant only so far as they operate as conditioning factors in social life’ (Wirth Reference Wirth1938, 6). However, another quotation from his seminal work has largely eclipsed his contextual insight in urban research, namely the definition of the city as a ‘relatively large, dense and permanent settlement of socially heterogeneous individuals’ (Wirth Reference Wirth1938, 8). More than 60 years later, it was the American archaeologist George Cowgill (Reference Cowgill2004, 526) who advocated a more flexible approach that looks for ‘a city’, rather than ‘the city’, and approaches urban ‘variables’ in a novel manner. His suggestion is ‘it is useful to think of urbanism as a cluster of variables that can be measured (if only roughly) on ordinal or interval scales, rather than as a discrete category’ (Cowgill Reference Cowgill2004, 527). Building on this study, yet a third influential figure, the American archaeologist Michael Smith (Reference Smith, Fernández-Götz and Krausse2016, 159 & table 10.1), has developed an approach to measuring ‘citi-ness’ in a non-constraining way. Yet these approaches have as yet had little effect on the mainstream notion of what is ‘urban’. What we have attempted is a fully worked-out example of a relational comparison between a megasite and a small Trypillia site (Gaydarska Reference Gaydarska2019b, section 6.3).

In summary, the major and complex issue for any project seeking to confront Trypillia megasites is the issue of scale. Just as Trypillia megasites posed a problem of how fifth-millennium communities could imagine a site 10—20 times the size of what they habitually built and occupied, the question of scale confronts each project with logistical, methodological and sampling issues of how to investigate such massive sites, such huge landscapes. A further question of scale also applies to one of the key Project research questions. One distinctive trend in post-1980s archaeology has been the focus on ever more detailed questions, based on ever more localized data sets—a trend that has prevented many interpretative archaeologists from making a creative contribution to research into urban origins and development. Just as transcending the limitations of face-to-face contacts and local networks was essential to the development of megasites, so our research project has sought to transcend issues of scale in our theoretical approach, relying on a relational and contextual approach to early cities which remains true to post-processual and interpretative principles. With these scalar issues in mind, it is time to turn to the three principal research questions which the Project addressed, beginning with our re-interpretation of Trypillia megasite lifeways.

Megasite lifeways

One of the most salient questions in megasite archaeology concerns what was happening on these massive sites—not just in very general terms (cattle husbandry, pit-digging, house-burning), but in integrated detail. Here, we turn to some of the key Project findings which, in our view, provide an alternative view of megasite functions to those found in most recent accounts (Müller et al. Reference Müller, Rassmann and Videiko2016b; Videiko Reference Videiko2013).

The introduction of modern geophysical techniques of investigation has had a dramatic impact on Trypillia research, with pedestrian fluxgate gradiometry utilized at Nebelivka (Chapman et al. Reference Chapman, Videiko and Gaydarska2014b) and vehicular caesium magnetometry at Taljanki, Majdanetske, Dobrovody and Apolianka (Rassmann et al. Reference Rassmann, Korvin-Piotrovsky, Videiko, Müller, Müller, Rassmann and Videiko2016). The Project has produced the only complete megasite plan so far, with a site area of 238 ha inside a shallow perimeter ditch (Fig. 1). All of the principal planning elements recognized in the first stage of megasite research (1970s–80s) have been confirmed in this second stage: the multiple concentric house circuits separated by large spaces, the inner radial streets leading to an open inner space, and the high frequencies of burnt houses and lower totals of unburnt/poorly burnt structures. In addition, recent geophysical research has identified several new classes of anomalies: (unburnt/poorly burnt houses, pits of differing sizes, large structures interpreted as public buildings, industrial features—kilns or cooking facilities, perimeter ditches, garden areas, palaeochannels and pathways), as well as new combinations of elements (Neighbourhoods, Squares and pit lines/groups). These new elements and combinations enabled the production of a much more dynamic narrative of megasites than was previously possible (Chapman et al. Reference Chapman, Videiko and Hale2014c; Gaydarska Reference Gaydarska and Gyucha2019a).

The total of 86 AMS dates would, in most circumstances, have enabled the Bayesian modelling of a robust internal chronology for the megasite, informing us on the relative start and end dates of the inner and outer circuits, the Squares and the inner radial streets. Unfortunately, the coincidence of dates with a wiggle in the calibration curve prevents an adequate internal sequencing, leaving us with the most probable dating for the overall occupation of 200 years (3970–3770 bc) (Fig. 4). This dating provides a secure chronology for part of Phase BII of the Trypillia group. Modelling of the number of houses and the length of occupation suggests that between a third and a sixth of all houses were occupied simultaneously (Supplementary Materials 7, online).

Figure 4.

The centre of the megasite plan comprises a 65 ha open area with no evidence for building or deposition—an area that could have contained almost any previous Trypillia site (Fig. 1). Monica Smith (Reference Smith2008) has demonstrated how open areas were active participants in the social space of complex sites, carefully managed and often with seasonal changes in function. The significance of the inner open area for major megasite ceremonials and regional-scale meetings has been overlooked in previous research.

At first sight, the regularity of the megasite plan suggests a hierarchical social order, with the power to impose a site-wide plan and control house-building in a regular layout (Rassmann et al. Reference Rassmann, Korvin-Piotrovsky, Videiko, Müller, Müller, Rassmann and Videiko2016). But the new geophysical investigations show that this regularity is deceptive, with 18 different forms of variability in plan detail (Table 2). This heterogeneity was seen in major plan elements, such as the distance between the outer and inner house circuits or the length of uninterrupted perimeter ditch sections, as well as minor planning elements, such as the presence and alignment of kinks in house circuits or the presence/absence of blocking streets cutting off radial streets from the inner open area. This high level of variability is a strong indicator that the Nebelivka plan was created from the bottom up rather than imposed hierarchically from the top down; indeed, there was so much planning heterogeneity that the opposite problem of social integration may have been more important to megasite survival.

Households, Neighbourhoods and Quarters

The improved resolution of Nebelivka's geophysical plan enabled a more structured interpretation of social space, with two additional nested levels between the levels of the house and the entire site—the Neighbourhood and the Quarter. At the smallest scale, houses made a statement about the whole Trypillia landscape, with construction materials collected from all parts of the landscape. Using information from our experimental house-building programme, the average 15×5 m house, mostly two-storeyed, would have taken 10–12 people one month to construct, with the largest houses taking twice as many person-days (Supplementary Materials SM2, Tables 1 & 2, online). Two-thirds of Nebelivka houses had been deliberately burnt to a high temperature, with the remainder weakly burnt or unburnt. The experimental finding that five to ten times more timber was required to burn a house as to build it confirms the notion of deliberate burning and has major implications for landscape impact. The burnt remains of about 10 per cent of the houses formed a low mound (Fig. 5), visible on the surface, unlike the burnt houses on a Balkan tell, which were usually levelled for the next building phase (Chapman & Gaydarska Reference Chapman, Gaydarska, Souvatzi, Baysal and Baysal2019). Steady accumulations of these ‘memory mounds’ across the site turned Nebelivka from a dwelling site to a mixture of settlement and ‘burnt house cemetery’.

Figure 5.

The grouping of houses into Neighbourhoods provided a local context of living in neighbourly proximity, with most households no more than 30 m from each other. Neighbourhoods are defined by a minimum of three houses separated at each end of the group from the next house (Fig. 1/inset). While up to 27 houses were found in the total of 153 Neighbourhoods, over half comprised three to seven houses. Larger Neighbourhoods suggested longer durations or greater demographic growth. The experimental programme estimates (Supplementary Materials SM2, Tables 1 & 2, online) show that seven houses of average size could have been built by 50 people in 40 days—perhaps by visitors to/residents at Nebelivka from a single home community. Local dynamism was evident in most Neighbourhoods in two ways—the wide range of house sizes and the variety of house-burning treatments—some completely burnt, others weakly fired (Fig. 1). Neighbourhoods provided a focus for multiple local identities which contrasted with, and may have posed a threat to, an overall Nebelivka identity which was central to the long-term success of the megasite. These local Neighbourhood identities dampened inter-household scalar tensions without necessarily decreasing scalar stress between neighbourhoods. Such higher-level disputes may have been solved at the next level up—the Quarter.

The 14 Nebelivka Quarters have been defined using multiple criteria (Chapman & Gaydarska Reference Chapman, Gaydarska, Fernández-Götz and Krausse2016) (Fig. 1). Covering an areal range of 5–20 ha, Quarters represented a scalar change in size, perhaps five or ten times the size of Neighbourhoods, and were larger than the average small Trypillia site. Each Quarter differed from other Quarters in size, number and size of houses and Neighbourhoods, suggesting origins from a variety of outside communities from whom visitors to Nebelivka had been drawn. The moderate differences between Quarters revealed through GINI coefficent analysis (see Supplementary Materials 4, online, for details) may be compared with the findings of greater house size variability by Quarter (see Supplementary Materials 5, online, for details); only two Quarters showed high scores in both analyses, underlining the modest social differentiation at this level. Both Neighbourhoods and Quarters helped to mitigate scalar stress (Johnson Reference Johnson, Renfrew, Rowlands & and Segraves1982) by a combination of living conditions at a local community scale and unprecedented opportunities for social interaction at a vast scale. However, despite variability in size and layout, a pioneering application of Visibility Graph Analysis using the software package Depthmap (see Supplementary Materials 3, online, for details) showed similar structuring of visibility and movement through space in all of the analysed Quarters (Fig. 6). This was particularly evident in the location of the public buildings termed ‘Assembly Houses’ in the most visually integrated and public zones of each Quarter. This finding indicates the tensions between an overall Nebelivka identity and the variability within Quarters highlighting a series of local identities.

Artifact studies

The Nebelivka excavations showed an archaeology of selective fragmentation and practices of episodic discard and deposition, as revealed through the taphonomic filter of the finds in structures and pits. While the discard of food refuse and lithic knapping debris indicated in situ practices, the majority of discarded and deposited remains do not provide a direct reflection of daily lives (a ‘living assemblage’), but rather constitute a series of interventions which brought together a range of people in deliberate depositional practices, such as the unusual but not rare event of a house-burning performance. This means that the deposited finds cannot be conceived as a direct reflection of, for example, household social differentiation, but rather in terms of contributions by different households to the ‘house death assemblage’, as a way of materializing inter-household relations.

Those maintenance activities which the Nebelivkans chose to exclude almost completely from their performances were food storage, plant-food preparation, cooking, the making of clothes and tool-making from bone, stone and metal. Special finds such as fired clay tokens and ornaments were also rarely deposited, although the overall density of figurine deposition matched that of small Trypillia sites (Gaydarska Reference Gaydarska, Kadrow and Müller2019c). A startling absence from burnt house assemblages was the functionally coherent pottery group indicating a ‘living assemblage’. While specialized production can be related to the construction of Assembly Houses and widespread painted pottery production, we can also identify skilled production by what Timothy Taylor called ‘limited interest groups’ of builders, potters, flint-knappers, bone tool-makers and figurine-makers (for discussion of term, see Chapman & Dolukhanov Reference Chapman, Dolukhanov, Chapman and Dolukhanov1993).

The scale of depositional practices at Nebelivka ranged from the single event, such as an episode of placing fragments of two vessels in a pit fill, to the massive communal ceremony of the burning of the megastructure—the largest Assembly House at Nebelivka and, at 60.5×18.3 m, the largest Trypillia structure yet found (Chapman et al. Reference Chapman, Videiko, Gaydarska, Burdo and Hale2014a) (Fig. 7). The megastructure deposition involved the placement of over 60 kg of pottery derived from at least 332 vessels—the majority for communal consumption—with variability in vessel fabric suggesting contributions from many households and Neighbourhoods. The most striking collective find was the group of 21 miniature vessels, with six vessels showing the first examples of graphite-painted decoration (Fig. 8/1) and a graphite wash ever found in the Trypillia group. One graphite-painted vessel was most probably an import from the Gumelniţa group in the Lower Danube valley (Fig. 8/3).

Megasite lithics: (1) flint rhomboid point; (2) flint lunate; (3–8) projectile points.

Small numbers of objects hint at ancestral relations with pre-megasite groups, such as the flint rhomboid point (Fig. 9/1), lunate (Fig. 9/2) and rare incised fine ware vessels (Fig. 8/3). Others still hint at individual production, such as the six flint projectile points all made in different ways (cf. Wiessner Reference Wiessner1983) (Fig. 9/4–9/9), and personal identity, such as the two figurines with realistic portrait heads (Fig. 8/2). But, for the most part, the producers and the people using the objects engaged with a broadly similar range of statements about how an object should be in relation to the Trypillia Big Other—thereby forming a stable, ‘Trypillia’ material world (cf. Wengrow Reference Wengrow2001). The clear preference for graded differences rather than presence/absence variation in pottery deposition indicates that a relational strategy of identity-construction was preferred, with the slow build-up of the remains of depositional events creating and maintaining the identities that related persons to all of their nested social contexts.

Nebelivka foodways and landscape

The megasite faunal sample showed the typical Middle Trypillia dominance of 90 per cent domesticates, with preferences for beef in some houses and a balanced mix of beef and mutton/lamb in other contexts (Gaydarska Reference Gaydarska2019b, section 5.3). The deposition of large quantities of animal bone in some pits suggested the prevalence of feasting in combination with artifact deposition. Despite the extensive use of flotation, the recovery rate of cereal grains and chaff was very low (six cereal grains in four excavation seasons!), with plant impressions on daub showing the common use of emmer and einkorn wheat, barley and pulses, as well as a neglect of the higher-yielding bread wheats and hexaploid barleys (Gaydarska Reference Gaydarska2019b, section 5.4). The combination of the absence of manuring scatters in the field-walking programme of the 5 km hinterland of the megasite (Supplementary Materials online, Fig. SM6) and the emphasis on hulled cereals from the botanical data suggests a relatively inefficient, traditional ‘Neolithic’ form of agriculture not at all consistent with mega-populations, with no sign of arable intensification on the chernozem soils. The intriguing paucity of coeval small sites within a 15 km radius (Nebbia Reference Nebbia2017) showed that the hinterland of Trypillia megasites contrasted strongly with that of early Near Eastern cities such as Uruk, with its dense network of supporting settlements (Adams Reference Adams1965).

A 6 m sediment core from a valley 250 m from the edge of the megasite has provided a dated sequence of local vegetation and megasite human impacts (Albert et al. Reference Albert, Innes, Kremenetskiy, Millard, Gaydarska, Nebbia and Chapman2019) (Fig. 10). An unexpected finding was the traces of cereal pollen and a charcoal peak indicating intensive landscape burning, which both pre-dated the megasite occupation. But the greatest surprise in the Nebelivka 1B proxy records was the modest human impact on the landscape of a megasite for which others had estimated a population of 6420–8560 people (Ohlrau et al. Reference Ohlrau, Dal Corso, Kirleis, Müller, Müller, Rassmann and Videiko2016, table 5). None of the five proxy records—deforestation, cereal pollen, micro-charcoal counts, soil erosion and water quality—showed more impact during the megasite occupation than before or after it (Fig. 10).

Figure 10.

The Nebelivka 1B core master diagram. (J. Innes.)

There is, thus, a paradox at the heart of the Trypillia megasites. On the one hand, the megasites constituted the largest settlements in fourth-millennium bc Europe, with site sizes up to 320 ha and estimated numbers of houses of almost 3000 on one site (Majdanetske: Rassmann et al. Reference Rassmann, Korvin-Piotrovsky, Videiko, Müller, Müller, Rassmann and Videiko2016). Their size, distinctive concentric settlement planning and signs of social complexity have reinforced the notion of massive, permanent, long-term dwelling. On the other hand, there is little evidence for the material or social differentiation one might have expected from such remarkable settlements. The houses fell within a narrow size range (Supplementary Materials 5, online) and there is a remarkable paucity of prestige goods, especially copper metallurgy, Spondylus ornaments and finely polished stonework. While specialists such as Diachenko (Reference Diachenko, Menotti and Korvin-Piotrovskiy2012; cf. Diachenko & Menotti Reference Diachenko and Menotti2012) have used gravity models to identify size-based settlement hierarchies, Nebbia's (Reference Nebbia2017) spatial analyses challenge this finding. Moreover, there is no evidence for a strong human impact on the local forest-steppe environment which would have followed from such postulated intensive dwelling. In short, there is a mismatch between the interpretation of a massive, permanent, long-term urban settlement and the settlement, environmental and material cultural evidence for a very different form of dwelling—smaller, less permanent and perhaps seasonal. The lack of a fine-grained internal chronology prevented the creation of a nuanced sequence of megasite development, instead prompting us to develop three alternative models for a smaller-scale form of megasite.

Alternative models for Nebelivka

The models were tested against, and met, four basic criteria: the total number of houses; the number of burnt houses; the low level of human impact as shown in the Nebelivka 1B core; and the number of coeval houses modelled by Millard (see Supplementary Materials 7, online). Two of the models are based upon the seasonal pattering of social life (cf. Wengrow & Graeber Reference Wengrow and Graeber2015), while the third relies on smaller-scale permanent settlement. Each model presents a variant on the Nebelivka site biography, which began with a well-established settlement network in the Southern Bug catchment, some of whose site clusters included megasites of up to 150 ha (for origins, see Chapman et al. Reference Chapman, Gaydarska and Nebbia2019), and a local settlement near the Nebelivka promontory, as attested in the Nebelivka 1B pollen core (Albert et al. Reference Albert, Innes, Kremenetskiy, Millard, Gaydarska, Nebbia and Chapman2019).

The Distributed Governance Model

The Distributed Governance Model (Gaydarska Reference Gaydarska2019b, section 6.1) (Fig. 11) envisages Nebelivka as a smaller but still permanent settlement with up to 400 contemporary houses, organized through a regional alliance of 10 descent groups which emerged from the existing settlement network. Multiple small settlements dispersed within a 100 km catchment area were affiliated to one of the 10 extended social groups. Each descent group drew on its wider network to complement megasite subsistence with food, salt, timber and other resources for one year before passing on the leadership role to another group. The responsibility of the smooth, heterarchical running of the megasite came with the power to take daily decisions on behalf of the people living in the settlement, but also their friends and relatives in the wider landscape. The descent groups built a single house circuit over the first five years, with expansion into a second circuit and the inner radial streets over the following decades. Seven to ten houses were build and burnt every year, keeping the number of contemporary houses around 400, while still accounting for the low environmental impact and the final footprint of 1445 houses. Decision-making at Nebelivka was taken through a council consisting of descent group representatives, with the leading descent group in any year organizing major festivals, such as the annual ‘Change of Descent Group’ ceremony and minor periodic ceremonies. But political power was distributed, with each descent group in control for one year in ten. The reason behind the emergence of this settlement form is the formalization of the experience gained during previous seasonal episodes of aggregation. The benefits of the increased potential for interaction, trade, and later specialized production inspired the initial experiment of a larger permanent co-habitation of heterogeneous groups. Once the sustainability of such a settlement was established via an off-site supply network, the vitality of this form of aggregation is witnessed by 600–800 years of continuity. The greatest strength of this model is that it fits well with the traditional view of permanent long-term occupation, but with greatly reduced population estimates. This model also best conforms to the construction of the solid timber-framed houses typical of all megasites.

Figure 11.

The Distributed Governance model. (C. Unwin.)

The Assembly Model

The Assembly Model (Nebbia et al. Reference Nebbia, Gaydarska, Millard and Chapman2018) (Fig. 12) interprets Nebelivka as a regional centre for large-scale assembly over one month per annum, with a small group of ‘Guardians’ living year-round as an agro-pastoral community and maintaining the centre outside assembly times. In comparison with the Pilgrimage Model's emphasis on religious practices and a much longer visiting season (see below), the Assembly Model exploited the shorter period for more concentrated interactions which brought a wide variety of benefits to participants, principally the opportunity to meet a far wider group of visitors than was ever possible elsewhere. The Assembly place developed out of the central settlements in previous (Phase BI) local settlement clusters. The site would have developed through the formation of Quarters, with five founded in each of the first and second generations and four more in the third generation—a slow development of the overall plan that was perhaps a weakness in this model. These Quarters had the dual purpose of materializing the local identities of the home communities through bottom-up planning, while at the same time providing an overall framework for the creation of a ‘central’ or ‘Nebelivka’ identity. These two identities were in tension throughout the use of the assembly site, with the Nebelivka identity supported by house-building and -burning activities, pit- and ditch-digging and communal feasting. But the ‘Nebelivka’ identity was dominant only at the time of the assembly, sustaining the seasonal re-structuring of society to form a regional political unit to create and run the assembly. The creation of a major assembly as the key event in the annual regional calendar would have been a big attraction to people over a wide area.

The Pilgrimage Model (Chapman & Gaydarska, Reference Chapman, Gaydarska, Stîrbu and Comşain press) (Fig. 13) is an extended version of the Assembly Model, but with a much longer, eight-month season and a more focused motivation based upon the Trypillia Big Other. This model is based upon extensive pre-existing social networks linking sites across regions, supported by the ubiquitous shared symbolic order of the Big Other. Following on from the assemblies of the earliest megasites in Phase BI, pilgrimage centres were selected for a range of different reasons by ritual leaders who became ‘site guardians’. It was these guardians who prepared the ground, organized the large-scale woodland management necessary for initial house-building and negotiated with other settlements for major contributions to the construction of the site.

The key feature of the model is the massive labour input required of ‘Pilgrim-Builders’ to construct an entire house circuit and dig the entire perimeter ditch in the first two seasons. The advantage for this effort was the creation of a spectacularly large pilgrimage centre which would have become famous across the whole Trypillia world. Thereafter, building rates became more tightly controlled, with home communities living in the same houses for a succession of one-month visits. In addition to the religious experience, healing, exchange and meeting with a diversity of people were all important parts of pilgrimage (McCorriston Reference McCorriston2011). This model provides the most cogent explanations for many of the planning elements of the megasite—not only the location and multiplicity of Assembly Houses, but also the concentric ditch and house circles and the radial streets, which are all interpreted as framing devices for processions from the outside of the site into the sacred open inner area.

Given that each model has its advantages and disadvantages, we have so far found it impossible to decide on any single model, leaving an element of ambiguity to the future interpretation of the Nebelivka megasite. Each model can best explain a key feature of the megasite plan—the Distributed Governance Model relates well to the multiplicity of timber-framed houses, the Assembly Model requires an inner open area for its principal meeting space, while the form of the concentric house circuits and inner radial streets would have created ideal processional spaces for the Pilgrimage Model. The Distributed Governance Model was inspired by K. Hirth's (Reference Hirth, Marcus and Sabloff2008) views on the modus operandi of the Mesoamerican altepetl and Hahn's (Reference Hahn, Kienlin and Zimmermann2012) work on segmentary societies in Africa, while pilgrimages have recently been discussed in comparable terms in British prehistory (Loveday Reference Loveday, Fowler, Harding and Hofmann2015) and the Near East (McCorriston Reference McCorriston2011). Equally, the importance of assembly sites has been widely discussed for Stonehenge (Parker Pearson Reference Parker Pearson2015), Angkor Wat (Lucero et al. Reference Lucero, Fletcher and Coningham2015), Cahokia (Pauketat & Emerson Reference Pauketat and Emerson2000) and in a special issue of World Archaeology (Semple Reference Semple2018).

The failure of any model to explain all of the megasite planning elements is an indicator that we cannot yet reject any model for the growth of the Nebelivka megasite. This conclusion inevitably complicates the debate over the urban status of megasites, to which we now turn.

Independent European urbanism

The initial impetus for pursuing an urban agenda in the interpretation of Nebelivka, and the megasites more generally, was the large settlement size. Very soon, however, it became obvious that such a path of box-ticking (e.g. large size being one of the few traits most urban commentators agree on) will relegate these sites to what they were before the Project—an exception that proves the rule (Liverani Reference Liverani and Clark2013). Since the accumulation of many strands of evidence proved the exceptional nature of Nebelivka, it was imperative that the exceptions now formed an alternative rule.

Building on Cowgill's (Reference Cowgill2004) insights, a proposition for measurement of ‘urban-ness’ was put forward that followed Cartwright and Runhardt's (Reference Cartwright, Runhardt, Cartwright and Montuschi2014) approach to measurement in the social sciences (Gaydarska Reference Gaydarska2016). Such an approach has been called ‘relational’, as its core premise is that various categories of sites, including urban, emerge in relation to each other rather than absolutely. Thus, for example what constitutes a city (or a town) in second-millennium bc China could not and should not be a mould applied to ad eleventh-century North America. Such a mould usually comes in either one of three definitions—Childe's (Reference Childe1950) check-list, Wirth's (Reference Wirth1938) sociological definition and Michael Smith's (Reference Smith2007) functional definition—or a variant on one of these three definitions or a combination of two or three of the definitions. For all the advantages such definitions have, they ‘flatten’ emerging phenomena, developed cities and sites with a long urban legacy into one single ‘idealized’ view of what should be considered as urban. The relational approach avoids such an amalgamation of individual and collective agencies, historical and landscape contexts and rapidly or slowly changing local circumstances by looking for emerging and recurring categories of sites in relation to preceding and contemporary settlement patterns. The difference, then, is not measured by presence/absence, absolute numbers or on a gradient scale, as suggested by Michael Smith (Reference Smith, Fernández-Götz and Krausse2016), but by identifying meaningful local markers in what Cartwright and Runhardt (Reference Cartwright, Runhardt, Cartwright and Montuschi2014) call the characterization of those social phenomena to be measured. Any characterization should meet the following conditions: it should be useful for its purpose, it is socially constructed, it should be not too general but it should also not create boundaries. The characterization of the category ‘urban’ in the Trypillian context in general, and Nebelivka in particular, has nine constituents—the territory to which a site is central, site size, population numbers, population heterogeneity, the concentration of skilled labour and management, the built environment and formalized spaces with special functions, the scale of subsistence, the potential to be a node and re-distribution centre in a wide-reaching exchange network and the overall social structure. The small (4.5 ha) Trypillia settlement of Grebeni (Kolesnikov Reference Kolesnikov1993) (Supplementary Materials 8, online) was then selected as a well-documented comparandum for the 238 ha Nebelivka along these nine lines, not just to point out obvious contrasts in scale, but to demonstrate the profound difference in lived experience and a wide range of social and technological potential (see Gaydarska Reference Gaydarska2019b, section 6.3).

As an example, we select only two—probably the most contentious—of the nine elements—the size of the sites and their population. The density of building on the smaller settlement was nine houses per hectare, providing enough space for small gardens and/or pens in the vicinity of each house. With a maximum population of c. 300 people (38 dwellings × 8 inhabitants), additional agricultural plots were needed to complement the plant-based component of their diet. Even the more distant of these fields would not have been more than half-an-hour's walk from the settlement. With just 38 houses, members from each neighbourhood would have seen each other daily, while inter-neighbourhood encounters were, if not a daily, then a weekly event. The residential density at Nebelivka was broadly similar or even lower (6 houses/ha) and although allotments and pens may have been nearby, the complementary arable plots and pastures to sustain a population in its thousands would have been located at a serious distance from the megasite—probably hours away. More people meant not only more food, water and waste, but also a more complex use of space not just for habitation, subsistence and rituals but requiring planning, logistics and management. And since the regular scale of face-to-face contacts on settlements rarely exceeded 450–500 people (Dunbar et al. Reference Dunbar, Gamble, Gowlett, Dunbar, Gamble and Gowlett2010; Forge Reference Forge, Ucko, Dimbleby and Tringham1972), the daily and weekly habitus of any occupant of Nebelivka may at first sight be like that in any small site; however, this number is 1/8 to 1/10 of the population of Nebelivka. While everyone could potentially have seen or met everyone else, people's interactions were probably channelled so that there were some more regular and other less regular meetings, introducing heterogeneity into social interactions and a diversity of household locations with differing degrees of connectivity.

The social, economic and personal implications of living on a small 4.5 ha and the rare >150 ha sites are so different that we argue that there was no possibility that the Nebelivka megasite was simply a very large example of a typical small rural settlement. Such an equation would be a categorical mistake, of the kind which suggests that aircraft carriers are simply very large examples of yachts. We argue that megasites were perceived, experienced and functioned in a very different way from any smaller previous and contemporary site. We do not know the emic name for megasites, but we call them ‘urban' since Trypillia megasites exhibited the same order of qualitative and quantitative differences from the typical small Trypillia settlement as the city of Uruk did from small tells in the Fertile Crescent, or Roman London from the villas of southeast England. The fact that this class of megasites can be dated to the earliest part of the fourth millennium bc—several centuries earlier than urban Uruk—offers further ground for considering their significance in world prehistory in a new light.

It is not just Trypillia megasites that have suffered an oversight in global urban debates. It is only in the last 10 years that the significance of a certain class of sites has finally been recognized. Low-density urbanism is now an acknowledged alternative trajectory of urban development in several regions in the world, such as Southeast Asia and Central America (Lucero et al. Reference Lucero, Fletcher and Coningham2015), with continuous expansion to include more anomalously large sites from across the globe (Fletcher & Kim Reference Fletcher and Kimsubmitted). The Trypillia megasites share all of the principal characteristics of the low-density urban sites (Fletcher Reference Fletcher2009), such as the short time taken from the origins of agriculture to the formation of urban communities, the transformation from higher-density to lower-density large sites, the importance of major building projects, kinship-based, house-oriented planning practices, seasonal settlement, the relative insignificance of the mortuary domain and the rarity of an urban legacy. This means that the Trypillia megasites were not only the earliest known urban sites in the world, but also the earliest known low-density urban sites in the world. But, whatever the label we attribute to the megasites, there remains the question of the origins of such remarkable sites.

The origins of Trypillia megasites

The North Pontic forest-steppe zone constituted a mosaic of deciduous woodland of lime, elm, oak and hazel interspersed with open parkland (Kremenetski Reference Kremenetski1995; Reference Kremenetski, Renfrew and Levine2003) in rolling loess plateaux rarely exceeding 250 masl, where some of the most fertile soils in Europe—the chernozems—had developed from the Mid-Holocene onwards (Shumilovskikh et al. Reference Shumilovskikh, Novenko and Giesecke2017). The Trypillia group were pioneering agro-pastoral communities which introduced domesticated crops and animals, large timber-framed houses and a wide range of novel material culture to the forest-steppe zone. A key area for a concentration of megasites, including the earliest examples, was the south Bug–Dnieper interfluve (Fig. 14). The absence of significant environmental differences between this zone and other forest-steppe areas with few or no megasites suggests that social rather than environmental factors were responsible for this concentration of megasites (Nebbia Reference Nebbia2017). So what was the cultural background from which they emerged? What were the changes in the Trypillia world to which megasites were a possible response? And what (dis)advantages did Trypillia megasites bring to their world?

Figure 14.

We can summarize the picture of Trypillia settlement at Phase BI/II (c. 4200–4000 bc), before the emergence of the first planned megasites, in the following way. The three key material traits of the Big Other—the house, the pottery and the figurines (Fig. 3)—were all demonstrably part of the initial agro-pastoral expansion east of the Dniester valley, proving to be the most attractive elements of Trypillia communities to the Forest Neolithic groups, who produced a limited range of fine wares but lacked figurines and rectangular houses. The BI/II network brought modest amounts of copper and Volhynian flint from the Western CT area. While some elements of what would become central elements of Phase BII megasite planning had already developed by Phase BI/II, they were not apparent on the largest sites and no Phase BI/II site showed more than a single ‘advanced’ planning element.

The emergence of large CT settlements by 4000 bc is part of two long-term settlement trends—landscape infilling northwards from the southern Bug valley and increased site clustering into small groups of sites, occasionally with more than one large site in the cluster (Supplementary Materials Figure SM9, online). As the first farmers in the North Pontic steppe, the CT network came into regular contact with local foragers (the so-called ‘Forest Neolithic’), who lived in small, possibly seasonal settlements (Kotova Reference Kotova2003). While the details of interactions between local foragers and incoming farmers remain unclear, the varied mix of site types and lifeways would have broadened the CT awareness of temporalities different from their own. The dramatic 15-fold increase in site sizes in a period of a few centuries depended on support from other, smaller settlements in a local buffering network (Halstead Reference Halstead, Halstead and O'Shea1982) and further exposed the CT network to the reality of inter-settlement differences. In these ways, it became possible to imagine massive sites with a temporality which differed from that of the usual settlement.

Three key innovations affecting the growth of CT settlements concerned the creation of coherent settlement plans, the introduction of painted pottery and changes in the importance of animal husbandry (Chapman et al. Reference Chapman, Gaydarska and Nebbia2019). Changes in settlement planning led to the novel combination of planning elements such as concentric house circles, inner radial streets and an inner open area into a single coherent megasite plan. The creation of two new types of large vessel widened the scope of household grain storage (Ellis Reference Ellis1984) and communal consumption and feasting. Decoration of fine wares in black paint required an expansion of exchange networks to obtain exotic manganese pigments. The combination of these changes led to a new class of fine painted wares more common than the rare prestige goods, leading in turn to new opportunities for domestic and public deposition. The preference for more domestic animals (over 90 per cent at Nebelivka: Gaydarska Reference Gaydarska2019b, section 5.3) gave households a greater control over animal keeping and opportunities for feasting. It was the integration of all three sets of practices at megasites that enabled scalar transformations in the quantity of people involved, the quantity of material involved and the quantity of house-building and -burning involved.

There is still a residual concern that these structural changes were necessary but insufficient factors in the emergence of these extraordinary sites. It is hard to envisage the scale of social interaction at an early megasite, with visitors meeting people from 30–50 home communities in contrast to the previous limited face-to-face engagements. In return for commitment to corporate projects (ditch- and pit-digging, the gathering of materials and house-building), early residents participated in an unprecedented range of special events, from ‘local’ Neighbourhood pit deposition and feasting to annual ‘global’ celebrations of the megasite itself. There was an element of success feeding success, with tales of the events, their scale and magnificence, spreading through the Trypillia network and attracting more and more visitors to the megasite. The stimulus of the megasite community for the creation of alliances made Nebelivka and other early megasites particularly special centres. It was this upward trend in alliance-formation and the richness of interactions that were the sparks leading to the emergence of megasites.

Given these important developments at early megasites, can we identify the key advantages to participating in megasite practices? The decision to develop a megasite into a more permanent arrangement was an agreement made by the whole network, as mediated by representatives of the many home communities whose members would settle at the megasite. This decision had several implications. The first was to consolidate alliances between those clans participating in the megasite dwelling, bringing those groups closer to each other than to other neighbouring clans. Secondly, the permanent arrangement led to a more formalized site plan which, in turn, supported the idea of a community identity. Thirdly, the increased place-value accruing to a megasite led to the general growth in importance of places where large gatherings were held. And, fourthly, the unprecedented scale of exchange occurring on such early megasites led to cumulative social advantages for those dwelling on such sites. The sum total of these advantages led to the attraction of megasite lifeways to a wider pool of people living in the extended Nebelivka network of 100 km radius. Problems of scalar stress would undoubtedly have caused more disputes than on a typical small Trypillia settlement. In the case of the two seasonally based models, the options of leaving early or simply moving to another part of a huge site were always open; disputes may well have been harder to manage or resolve in the third, permanent settlement model (see above).

In summary, the diversity of pre-megasite settlement experience in the southern Bug–Dnieper interfluve provided settlers with the possibility of imagining different kinds of site—small settlements and large, seasonal or permanent centres of assembly—which enabled the emergence of the megasites. Major changes in settlement planning and painted pottery production, as well as changes in animal keeping, can be closely related to the origins of megasites. But the key innovation which co-emerged with megasites was the potential for an unprecedented scale of interaction—whether personal (exchange, feasting) or institutional (alliance formation).
