In this article, the ways in which hobby metal detectorists searching for protected objects in the ploughsoil and archaeologists in Norway have collaborated and communicated throughout the public history of metal detecting in the country is outlined and problematized. Due to the opinions of individual archaeologists working in key positions and the autonomy of the country's local and regional management institutions, there are huge variations in both attitudes and practices toward metal detecting and its practitioners. In some areas, metal detectorists are allowed to search more or less freely, whereas in others, entire fields are protected after a few finds, making continued detecting without formal approval from the authorities illegal. Because of this, and the extreme difference in the activity level of individual detectorists, the number of recorded detecting finds varies immensely across county and regional borders. I suggest that channels for collaboration and communication be formalized and that a national and therefore uniform public reporting system be realized—given that it is, for the time being, largely up to individual archaeologists whether some of the country's most active citizen scientists are equally treated by the archaeological heritage management system in Norway.

This article considers the relevance of the Society for American Archaeology's 2018 “Statement on Collaboration with Responsible and Responsive Stewards of the Past” for imported antiquities (specifically, “classical” ones—that is, from Mediterranean regions). Various practical, legal, and ethical differences between collecting imported versus domestic objects make it difficult to identify “responsive and responsible stewards” of the former. An obstacle to responsible stewardship of privately owned classical collections—and to collaboration between classical archaeologists and collectors—is the 2008 acquisition guidelines issued by the two leading professional organizations in the museum field. I argue that the best home for unprovenienced and poorly provenienced antiquities collections is in university museums, where their complicated object biographies can be fully researched, taught, and displayed.

Through our research at Bahía Yendegaia on the Beagle Channel in southernmost Patagonia—the ancestral territory of the Yagán people—we discovered the first rock art site on Tierra del Fuego Island. The geometric visual images found at Yendegaia Rockshelter present motifs and compositions analogous to those recorded at other sites on the southern archipelago associated with the marine hunter-gatherer tradition. They also show graphic similarities to the rock art paintings attributed to terrestrial hunter-gatherer populations from the Pali Aike volcanic field, located on the north side of the Strait of Magellan in mainland Patagonia. Both, however, display quantitative differences, which suggest that they emerged from different visual traditions but from the same field of graphic solutions. Navigational technology enabled the canoe-faring Fuegian people to have long-distance mobility and to maintain a flow of social information mediated via visual imagery expressed in material forms, such as rock art and expressions of portable art. Ethnohistoric reports suggest a cooperative social interaction more than a competitive one. This cooperative social dynamic would have been necessary for the survival of marine societies in the harsh environmental conditions characteristic of the southern part of south Patagonia.

Although the legal conditions are perceived as restrictive, metal detecting has become a popular activity in the Czech Republic. In 2017, a questionnaire survey revealed that a significant segment of this community is made up of passionate people interested in history and archaeology. The majority of professional archaeologists consider metal-detecting finds to be important and believe that cooperation with metal detectorists is necessary, beneficial, and acceptable. A collaborative project called “Joint Forces in Order to Discover the Common Archaeological Heritage of the South Moravian Region” aims to create conditions for citizen science among the metal detectorists in the region. By using tools such as expert workshops for the employees of professional institutions, meetings, educational workshops and field activities with interested members of the public, and production and distribution of printed and digital information materials, the partners in the program have long endeavored to improve the mutual understanding of all relevant actors of society and administration. The creation of circles of citizen collaborators is in progress in several archaeological institutions; nevertheless, this process is far from over. In 2020, with the creation of the Portal of Amateur Collaborators, this activity acquired a unified digital scheme for the registration of finds.

During the excavations of the team of the University of Chieti in the area of Ain Hofra, in the East necropolis of Cyrene, several interesting sculptures were found in tombs A and C, also called the Tomb of the Sarcophagi and the Tomb of the Sculptures. In this paper a specific find from Tomb A is presented, as it is a rare example of a Mithraic relief from a private funerary context. The find has only previously been published for the translation and presentation of the inscription; however, an analysis and interpretation of the relief together with the inscription has never been tackled. The very fragmentary lid is made of white marble, presenting a very lively iconographic sequence of Mithraic schemata, in combination with a metrical inscription within a central tabula ansata. The find context is particularly monumental and is characterized by two Temple Tombs built in ashlar masonry located on the plateau of Ain Hofra overlooking the wadi (canyon) and the fertile terraces below. This multidisciplinary article looks at the iconographic elements, the epigraphic implications and the monumental context of the Mithraic reliefs.

Hobby metal detectorists search for archaeological finds as individuals and within groups, the latter being the focus of this article. Such groups come together as “clubs” and “meetings,” but also as part of large, often commercially run events typically known as “rallies.” All these activities are attractive to detectorists because they provide them with access to land to search, along with the promise of making interesting (even valuable) discoveries, and they have a social dimension. They are common in England and also well established in several countries in northwest Europe, partly due to changing legislation. Although policies and mechanisms are often in place for collaboration with individual detectorists and even local metal-detecting clubs, larger events (not least, the large-scale commercial rallies increasingly occurring in England) present challenges for professional archaeologists, specifically in relation to the capacity to properly record finds and manage potential damage to the historic environment. To respond appropriately to these changes, a greater understanding of detectorists’ events is needed. For this reason, we explore and define the scale, nature, and diversity of group events, relating them to different legislative and cultural contexts in Flanders (Belgium), England (and Wales), and Finland. Subsequently, we outline challenges associated with group events and identify possible ways forward.

It is generally believed that Tripolitanian historiography began with the chronicle of Muḥammad b. Ghalbūn in the first half of the 12th century AH/18th century AD, before expanding in the 13th/19th. This pattern tends to forget that other players – unfortunately now lost – predated that modern historical writing. The oldest one seems to be related to a Tripolitanian scholar, ʽAlī b. ʽAbd Allāh b. Maḥbūb al-Ṭarābulusī, who lived at the end of the 5th/11th century/beginning of the 6th/12th, who settled in the East and wrote a short chronicle to give an account of the history of his hometown. This article aims to gather all the data related to him and his works, to show the formation of a local memory in the wake of the political autonomy acquired by Tripoli from the beginning of the 5th/11th century.

Evidence for working rock crystal, a rare form of water-clear type of quartz, is occasionally recovered from prehistoric sites in Britain and Ireland, however, very little has been written on the specific methods of working this material, and its potential significance in the past. This paper presents the first synthesis of rock crystal evidence from Britain and Ireland, before examining a new assemblage from the Early Neolithic site of Dorstone Hill, Herefordshire. This outlines a methodology for analysing and interpreting this unusual material, and, through comparison with the flint assemblage, examines the specific uses and treatments of this material. Far from being used to make tools, we argue the distinctive and exotic rock crystal was being used to create distinctive and memorable moments, binding individuals together, forging local identities, and connecting the living and the dead.

This article addresses the lack of literature on grinding and crushing techniques and its equipment in Africa Proconsularis. A new typology is presented, along with their geographical distribution. The types of stones used are also discussed, in relation to provenance, suitability and technological innovations. The conclusion questions what we know and what future research needs to address.
