a city of Macedonia, an Athenian colony, on the Strymon, but on which side is not so certain: Pliny places it in Macedonia, on this side; but Scylax, in Thrace, on the other. The name of the town, *Amphipolis*, however, seems to reconcile their difference; because, as Thucydides observes, it was washed 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 *Rivus*, from the Nine Ways, (Thucydides, Herodotus.) The citizens were called *Amphipolitani*, (Livy.) It was afterwards called *Christopolis*; now *Christopoli*, or *Chifopoli*, (Holinus.)

a town of Syria, on the Euphrates, built by Seleucus, called by the Syrians *Tumeda*, (Stephanus;) the same with *Thapsacus*, (Pliny;) and supposed to have been only renewed and adorned by Seleucus, because long famous before his time, (Xenophon.)

**AMPHIPPUS**, in Grecian antiquity, soldiers who, in war, used two horses without saddles, and were dexterous enough to lead from one to the other.
