Following two Delta Conferences (funded through the British Academy Special Project of the Egypt Exploration Society), the first online in 2021 and the other at Ain Shams University in 2023, selected papers have been gathered in this first volume of a new series of Delta Reports. They detail archaeological work in the north of Egypt in the form of a series of reports from Predynastic sites at Minshat Abu Omar and the eastern delta, survey work in the Wadi Tumilat, and ongoing work at the fortress of Tjaru (Tell Hebou II) and the Tell el Basta ka-chapel of Pepi II. On the western side of the Delta, Ptolemaic and Roman material is reviewed from Tell Trugi, Taposiris-Magna and Naukratis. An overview article by the BEAST project discusses a method for calculating population distributions in the delta over the whole of ancient times to provide a broader context for the archaeological reports.
