AMPHIPOLIS, in Ancient Geography, a city of Macedonia, an Athenian colony, on the Strymon, but on which side is not certain: Pliny places it in Macedonia, on this side; but Scylax, in Thrace, on the other. The name of the town, Ambipolis, however, seems to reconcile their difference; because, as Thucydides observes, it was walled on two sides by the Strymon, which dividing itself into two channels, the city stood in the middle, and on the side towards the sea there was a wall built from channel to channel. Its ancient name was Enna edu, the Nine ways (Thucydides, Herodotus.) The citizens were called Ambipolitani, (Livy.) It was afterwards called Crisopoli; now Chrysopoli, or Chisopoli, (Holtznius.)
