This article introduces a votive inscription unearthed among the ruins of one of the building groups, dated Ist century BC – Ist century AD in the light of the findings and located in the pronaos of the Doric temple called the Hellenistic Temple, during 2023 excavations in the city of Phaselis. This inscription was dedicated by Krotos, the son of Agathion, to Sarapis, Isis and Anubis. Since the name Krotos is documented in various papyrus texts, it has been suggested that the person who made the dedication may have been one of the merchants from Egypt as supported by the similar votive inscriptions from Delos. In this context, the worship to these gods in the Hellenistic period was revealed, especially by examining the examples found in the port cities of the Aegean islands and the southwestern Anatolian coast. At the same time, based on the epigraphic, papyrological, numismatic and archaeological evidence obtained from both the Phaselis and Egypt, the interaction of the city of Phaselis with Egypt since its foundation and continuing throughout the Hellenistic period is mentioned.
