Priapos was founded by the god of the same name, who was the god of fertility and whose image is often not safe for work. Strabo writes that the city had good wine. In 334 BCE, Alexander sent a general to take the city and it surrendered without complaint.
Plutarch mentions that some soldiers of Mithridates tore down a temple of Artemis in Priapos and then perished in a tempest caused by the gods.
Strabo discusses the city a number of times, and specifically mentions that it lost territory to Parion.
