APOLLONIA, the name of several ancient cities, particularly of a colony of the Milesians in Thrace, from which Lucullus took away a colossus of Apollo, and placed it in the capitol. The greatest part of the town was situated in a small island in the Euxine, in which was a temple of Apollo (Strabo). Pliny says the colossus was 30 cubits high, and cost 500 talents. There was also an Apollonia at Mount Parnassus, near Delphi (Stephanus). Troezen was formerly called Apollonia.
