This article discusses the origin of the three dynastic settlements, which the Ptolemies (re) founded in Cyrenaica: Arsinoe-Taucheira, Ptolemais near Barca and Berenike near Euesperides. The evidence for the dating of the foundation of Ptolemais is re-examined and a papyrological text introduced, which has so far been ignored by previous scholars. This text unambiguously attests citizens of Ptolemais near Barca as early as 252 BC in Egypt. It refutes the commonly accepted argument that all three Ptolemaic cities were founded under Ptolemy III Euergetes (246-221 BC) and within the same framework of administrative-political concerns. It will be suggested that Ptolemy I Soter had the motifs, opportunity and resources to found Ptolemais as early as the end of the fourth century BC. Several papyri further emphasise that despite the almost simultaneous demise of Euesperides and rise of Berenike nearby, ethnic designations for these two cities were simultaneously in use throughout Ptolemaic Egypt until at least the end of the third century BC.
