Pythion (Greek: Πύθιον) or Pythium, also Pythoion (Πύθοιον) was a city and polis (city-state)[1] of Perrhaebia in ancient Thessaly, situated at the foot of Mount Olympus, and forming a Tripolis with the two neighbouring towns of Azorus and Doliche. Pythion derived its name from a temple of Apollo Pythius situated on one of the summits of Olympus, as we learn from an epigram of Xeinagoras, a Greek mathematician, who measured the height of Olympus from these parts.[2] Games were also celebrated here in honour of Apollo.[3]
