Understanding biotic responses to environmental changes will help identify extinction risks and direct conservation efforts to mitigate negative effects associated with anthropogenic-induced environmental changes. Here we use the Quaternary fossil record of mole salamanders (Ambystoma) from the southwestern United States and northern Mexico to reveal geographic patterns of extirpation since the Pleistocene. Ambystoma are known to have previously inhabited regions of central Texas on the Edwards Plateau; however, they are largely absent from the region today. We used a well-dated fossil record of Ambystoma from Hall’s Cave combined with other fossil sites in the region to deduce why Ambystoma was ultimately extirpated from the Edwards Plateau and to test hypotheses related to temperature-driven body-size changes in line with the temperature–size rule. We propose that Ambystoma was likely extirpated from the region due to changing temperature and precipitation regimes that caused increased mortality and disruptions to breeding and larval development. We found some support for decreased body size in Ambystoma with increased temperature during the late Pleistocene, suggesting that body size may be an important feature to monitor in modern populations of Ambystoma as salamanders become subjected to increasingly hotter temperatures in the coming decades.
The Palmyrene banqueting tesserae, clay entrance tickets to religious banquets, have been revisited over and over again since the publication of the RTP in 1955. These small but often elaborate objects have been used as lenses into Palmyra’s religious life and the general organization of social, cultural and religious life in the city. However, only in recent years have they become the object of new detailed studies, which aim to systematically examine this unique group of objects within their local context. In this contribution, the focus is on disentangling the tesserae as physical objects to be used, touched and looked at; in particular it seeks to understand a facet of their rich iconographic repertoire, which in so many ways stands in contrast to the otherwise allegedly streamlined visual art repertoire found at Palmyra, namely that of the signet seal impressions. These signet seal impressions were impressed on many of the tesserae, most likely by the sponsor of the banquet, who left his personal mark on the tickets. The seal impressions give us insight into the images circulating in Palmyra in the Roman period in a material group, which today is almost lost to us, namely the glyptic art.
Terrestrial gastropods can incorporate carbon from multiple sources, including 14C-depleted carbonate from limestone, known as the “Limestone Problem” (Goodfriend and Stipp 1983). This affects the reliability of 14C dating on terrestrial snails, and varies by species, habitat, and physiography, necessitating local validation studies. This study assessed whether two land snail taxa common in carbonate terrains of Florida (USA) accurately reflect atmospheric 14C concentration at the time of biomineralization, a necessary condition for accurate dating, or if they incorporate pre-aged carbon, leading to radiocarbon ages that are “too old.” Radiocarbon measurements were made on 11 modern, known-age specimens (collected 1967–2015) of the rosy wolfsnail (Euglandina rosea) and flatcoil (Polygyra spp.) snails, and results were compared to expected atmospheric values based on the Bomb21 NH2 calibration dataset (Hua et al. 2022). Specimens from carbonate terrains had significantly lower 14C activity than the contemporaneous atmosphere, while those from sandy terrains showed no such offsets. The magnitude of the offset varied by taxon. Flatcoils from carbonate terrains had the most unreliable dates, overestimated by 1350 ± 740 14C yr on average. Rosy wolfsnails from carbonate terrains had smaller offsets, overestimating by 270 ± 130 14C yr on average. The results suggest land snails from Florida will incorporate significant and variable amounts of pre-aged or “dead” carbonate in their shells if it is present in the landscape.
This chapter focuses on Palmyra’s choices in weaving a wider network of social ties to both the Mediterranean and eastern world in order to enjoy the recognizable success that lasted several centuries. It gleans evidence of the presence of Palmyrenes in the Mediterranean, Egypt, the Persian Gulf and Indian Ocean, before discussing the observable strategies in terms of strengthening commercial ties or choices in items of trade based on their high commercial value and lightness in terms of transport, such as silk or pearls.
This chapter explores the sacral aspects of Achaemenid Persian kingship. It attempts to precisely illuminate the ruler’s relationship with the divine and to demonstrate that the assumption of priestly prerogatives was an important aspect of his office. To better appreciate the political function of religion, this study provides cultural and historical contexts for the royal appropriation of sacral attributes. It further contributes to the recent field of study regarding a possible soteriological dimension to Achaemenid ideology by assessing and synthesising new and previously cited evidence for the existence of such an element, as well as its possible applications.
Little is known about the Jewish presence Roman time Palmyra: the remains of a synagogue and other archaeological and epigraphic data indicate that Jews lived in Palmyra. Their presence is confirmed by onomastics. About twenty biblical names are preserved in inscriptions from Palmyra. Others are found in epitaphs from Beth She‘arim catacombs. However, Palmyrene Jews also bore Palmyrene names, and therefore it is not always easy to reconstruct identity and religious affiliation. Therefore the epigraphic data indicate only a small portion of what must have been the Jewish population of Palmyra. Examples of the mobility of Palmyrene Jews are illustrated by their presence in the Roman army, by first century BC–first century AD ossuaries from Palestine with Palmyrene epitaphs and by Palmyrene onomastics in Aramaic and Greek epitaphs. Westward mobility of Palmyrenes is displayed in an Aramaic Bar Kokhba letter mentioning an individual of Palmyrene origin. Finally, fourth to seventh centuries AD documents from Israel and Jordan written in Hebrew, Aramaic or Greek show the persistence and fortune, within Jewish and proto-Christian communities, of the name Zenobios and Zenobia, an onomastic choice inspired by the foremost protagonist of the last phase of Palmyrene history.
Mountains figure prominently in Mesoamerican cosmogeny, and a deep history of pilgrimage and worship surrounds many, though few have been systematically investigated using modern archaeological methods. Here, the authors present results from the lidar mapping and surface survey of a plateau at the summit of Cerro Patlachique, located at the southern limit of the Teotihuacan Valley, Mexico. While ceramic typology establishes Cerro Patlachique as a site of pilgrimage before, during and after the occupation of Teotihuacan, the documentation of 34 carved monuments substantially expands the existing corpus and identifies the summit as a place of convocation with water deities.
This essay explores the evolution of the discourse of leadership in pre-imperial (pre-221 bc) China. I show how the formation of the ideology of monarchism during the formative age of traditional Chinese culture was accompanied by subtle bifurcation between the concept of the ruler and that of the leader. Chinese intellectuals of what is often dubbed the age of the Hundred Schools of Thought agreed that the monarch should possess absolute power, but they had carefully shaped the monarch’s image in the way that allowed much leverage to the members of their own stratum. A subtle and yet well-pronounced bifurcation between political leadership of the monarch and the moral and intellectual leadership of an outstanding minister or an aspiring minister remained one of the major features of Chinese political thought and political culture for millennia to come.
For Cicero, effective Republican leadership entailed both morality and agency. Morality meant actions that supported the Republic, while agency was required for such actions to be carried out. It is difficult to subsume any theory of leadership under a single word, but I argue that Cicero’s leadership theory can be signified by consilium. This term encapsulates the best mental and moral aspects of leadership as well as the actions and results of acting on behalf of the Republic. It is inherently tied to the practice of Republican politics, a practice that was fundamentally transactional. Cicero used this idea of consilium to support his acceptance of Octavian as an ally against Antony. According to his theory of consilium, Cicero acted correctly against Antony, but Octavian ultimately exposed the flaws in Cicero’s theory when he refused to participate in traditional Republican transactional politics.
