Tackling erosion-accumulation events in a moat sequence from a unique Ottoman memorial place (Szigetvár, SW Hungary) using 14C and geoarcheological data

One of the most influential rulers of the sixteenth century, Sultan Suleyman I, passed away and was buried temporarily near the fortress of Szigetvár in SW Hungary in 1566. Later, a memorial place was erected on the site in the second half of the sixteenth century. The complex was surrounded by a palisade system and a moat on its northern side. The site was fully destroyed in 1692, and the exact location vanished with time. Recent investigations of historical sources complemented by geophysical, archeological, and geoarcheological investigations managed to identify the location of the site, and probe corings revealed the moat system. This study presents the results of complex chronological, sedimentological, and geochemical investigations done on the sediments accumulated in the moat. Based on geoarcheological data, two major changes could have been noted in the nature of the deposit marking erosion and transportation of soil from the banks of the moat. Elevated concentrations of Fe and K, and high MS values mark the effects of fire on the deposit and accumulation of flue ash. A rise in heavy metals in these horizons is attributable to anthropogenic sources related to the destruction of the site. Chronological data comes from dateable artifacts reposited and 14C dates of charred cereal seeds. A Bayesian age model built using 14C ages constrained by written historical data on site use helped us to determine the age of moat construction and the referred erosion-accumulation events. The older event was dated around 1670, which is in line with historical records of the first siege of Szigetvár. The second event postdates 1684 and thus must correspond to the time of the site’s final siege and later destruction.

Comparison of human and faunal enamel isotopes reveals diverse paleodiet and exchange patterns at the highland Maya Site of Kaminaljuyu, Guatemala

This study provides an isotopic examination of both human and animal paleodiets and mobility patterns at a highland Maya community. Kaminaljuyu, Guatemala, was a large Prehispanic center located in a distinctly cooler, drier setting compared with the majority of Maya sites in the surrounding lowlands. Previous archaeological research at Kaminaljuyu revealed it played an important political and economic role in the Maya region, assisting in the obsidian trade network and maintaining ties with communities as far away as Teotihuacan in central Mexico. By examining the strontium (87Sr/86Sr), carbon (δ13C), and oxygen (δ18O) isotope values from dental enamel of humans and terrestrial mammals at the site, this study provides direct evidence of long-distance animal trade, explores the nature and timing of such activities, and compares highland dietary patterns with faunal studies in the lowlands. Our results indicate that isotopically non-local humans and animals are most frequently found in special and ceremonial contexts, indicating that long-distance movements of people and products were motivated for politically or ritually significant events. Although dietary patterns showed cross-species variation, diets within species were similar between highland and lowland settings.
