(Θετίδειον; Thetídeion). Sanctuary to Thetis in the territory of Pharsalus. Shortly before the battle of Cynoscephalae in 197 BC the Roman and Macedonian armies camped near there (Pol. 18,20; Liv. 33,6,10). The location is problematic: the area near Dasolophos (formerly Bekides), on the basis of the route of the march, and the lands around modern Thetidion (formerly Alchami), because of ancient remains, are possibilities.
