Proconnesus or Prokonnesos (Ancient Greek: Προκόννησος), also spelt Proeconesus or Proikonnesos (Προικόνησος), was a Greek town on the southwestern shore of Proconnesus island. Aristeas, the poet of the Arimaspeia, was a native. This town, which was a colony of the Milesians, was burnt by a Phoenician fleet, acting under the orders of Persian king Darius I. Strabo distinguishes between old and new Proconnesus. The inhabitants of Cyzicus, at a time which we cannot ascertain, forced the Proconnesians to dwell together with them, and transferred the statue of the goddess Dindymene to their own city.
