The details of the foundation and eventual abandonment of the city are unknown. From the end of the fifth century BC, the town minted staters that had both Greek and Aramaic inscriptions, one of which bears the name of the Persian satrapPharnabazus. The Nagidos mint used a grape cluster as a symbol on the reverse. The goddessAphrodite appears most often on the coins of Nagidos, indicating that her sanctuary must have been the most important in the city.
The Hellenistic period and the foundation of Arsinoe
In 333 BC the city was conquered along with the rest of Cilicia by Alexander the Great. After his death Cilicia briefly came under the control of the Seleucid Empire. Together with Mallos the city participated in the foundation of Antioch on the Maeandersomewhere between 281 and 270 BC. In approximately 270 BC Cilicia was conquered by the Ptolemaic Empire during the Syrian Wars. In this period the city of Arsinoe was founded between 279 and 260–253 BC on land taken from Nagidos by Aetos, the Ptolemaic strategos or military governor of Cilicia. Aetos was succeeded as strategos by his son Thraseas. At that time the Nagidians still refused to recognize the settlers of Arsinoe as the new owners of the land. To resolve the dispute Thraseas requested Nagidos to cede the land to Arsinoe, which the city agreed to. In exchange the citizens of Arsinoe became apoikoi of Nagidos, which meant that their city would be independent from Nagidos. Both cities exchanged isopoliteia so that the citizens of both cities enjoyed a single citizenship. Designating the citizens of Arsinoe as apokoi of Nagidos meant that Nagidos was treated as the mother city of Arsinoe. Christian Habicht interprets this as a diplomatic move of Thraseas to appease Nagidos for its loss of territory. John K. Davies gives a slightly different chronology, estimating the foundation of Arsinoe to have taken place probably in the 260s BC. He writes that Cilicia was then temporarily lost to the Seleucids but retaken by Ptolemaics in the 240s. According to him the dispute over the land occurred after the reestablishment of Ptolemaic control and the Arsinoeis appealed to Thraseas some time after 238 BC. Along with the rest of Cilicia, Nagidos came under Seleucid rule in 197 BC. Excavations have shown that the city was abandoned towards the middle of the second century BC. Possibly this was a consequence of the activities of the Cilician pirates.
Excavations
Ancient sources gave an important clue to the location of Nagidos because they mention the island Nagidoussa lay offshore from the city. This allowed the Austrian archaeologists Rudolf Heberdey and Adolf Wilhelm to identify the site at its current location in 1891. In the 1930s a Swedish expedition carried out explorations. In 1986 the museum of Anamur discovered 24 graves, the oldest dating back to the fifth century BC.
