Tritaea or Tritaia (Ancient Greek: Τριταία)[1] was a polis (city-state)[2] of Achaea, and the most inland of the 12 Achaean cities, was distant 120 stadia from Pharae. According Pausanias, Tritaea's foundation was said to be due to either: Celbidas, who came from Cumae; or Melanippus, a son of Ares and Triteia, herself a daughter of Triton and priestess of Athena, and that Melanippus named the town after his mother.[3]
It was one of the four cities that took the lead in reviving the Achaean League during the 124th Olympiad (c. 280 BCE).[4] In the Social War it suffered from the attacks of the Aetolians and Eleians.[5] Its territory was annexed to Patrae by Augustus, when he made the latter city a colony after the Battle of Actium.[6] Tritaea was home to Agesarchus of Tritaea, an Olympic victor around 120 BCE, whose statue graced Olympia.
Highlights of Pausanias's visit in the 2nd century included a white marble tomb with paintings by Nicias in the vicinity of the city. Also in the city there was a sanctuary of the gods, with images of clay and in honour of which an annual feast was celebrated, and also a temple of Athena with a stone image that had replaced another that the Romans had taken to Rome. There sacrifices were celebrated to Ares and to Triteia.[6] In Triteia there was a sanctuary of the gods called Almighty (Μεγίστων θεῶν), and their statues in the sanctuary were made of clay. In honor of these gods every year a festival was held.[7]
The site of Tritaea is located at modern Agia Marina.[8][9]
