RT Journal Article T1 Diet and food strategies in a southern al-Andalusian urban environment during Caliphal period, ecija, Sevilla A1 Inskip, Sara A1 Carroll, Gina A1 Waters Rist, Andrea A1 López Costas, Olalla K1 Al-Andalus K1 Islamic archaeology K1 Isotope K1 Medieval K1 Apatite K1 Collagen AB The Iberian medieval period is unique in European history due to the widespread socio-cultural changes that took place after thearrival of Arabs, Berbers and Islam in 711 AD. Recently, isotopic research has been insightful on dietary shifts, status, resourceavailability and the impact of environment. However, there is no published isotopic research exploring these factors in southernIberian populations, and as the history of this area differs to the northern regions, this leaves a significant lacuna in ourknowledge. This research fills this gap via isotopic analysis of human (n = 66) and faunal (n = 13) samples from the 9th to the13th century Écija, a town renowned for high temperatures and salinity. Stable carbon (δ13C) and nitrogen (δ15N) isotopes wereassessed from rib collagen, while carbon (δ13C) values were derived from enamel apatite. Human diet is consistent with C3 plantconsumption with a very minor contribution of C4 plants, an interesting feature considering the suitability of Écija to C4 cerealproduction. δ15N values vary among adults, which may suggest variable animal protein consumption or isotopic variation withinanimal species due to differences in foddering. Consideration of δ13C collagen and apatite values together may indicate sugarcaneconsumption, while moderate δ15N values do not suggest a strong aridity or salinity effect. Comparison with other Iberian groupsshows similarities relating to time and location rather than by religion, although more multi-isotopic studies combined withzooarchaeology and botany may reveal subtle differences unobservable in carbon and nitrogen collagen studies alone.
