Predynastic and Early Dynastic plant economy in the Nile Delta: archaeobotanical evidence from Tell el-Iswid

Abstract The large-scale excavation at the prehistoric site of Tell el-Iswid made it possible to undertake a systematic archaeobotanical study of different structures covering the Predynastic and Early Dynastic period (Lower Egyptian Cultures, i.e. Buto II (3500−3300 bc ) to Naqada III Culture (3300−2900 bc )). Here we present the results of the analysis of carpological remains preserved mostly in a charred state and coming from 62 samples processed by manual flotation, with total volume of 615 L and containing a total of 9,672 identifiable and quantifiable items. A further ca. 650 wood fragments (or woody vegetative remains) were subject to anthracological analysis. Besides the aim of overall characterisation and exploration of the plant economy of the site, the macrobotanical assemblages were also considered in relation to the structures from which they were uncovered. The study revealed that the agricultural economy of both studied periods relied on emmer, barley, lentils, and pea, but from Early Dynastic times onwards barley and pulses gained more importance, along with flax ( Linum usitatissimum ) and condiments (like Anethum graveolens and cf. Origanum sp.), which occur first during this period at the site. Together with the cultivated fields, the surrounding wetlands were also an important part of the plant resources utilized at the site. The stems of Phragmites are the most common among the anthracological remains, together with a small proportion of Tamarix and Acacia charcoal fragments. The overall composition of the plant assemblages (charred and mineralised chaff, small weed or wild growing seeds capable of passing herbivore digestion, dung fragments, awns) suggest that the major source of the retrieved plant remains was dung fuel.
