ÆGIUM, in Ancient Geography, a town of Æchaia Properia, five miles from the place where Helice flood, and famous for the council of the Æcheans, which usually met there on account either of the dignity or commodious situation of the place. It was also famous for the worship of Olympicus Zeus, Conventional Jupiter, and of Panachean Ceres. The territory of Ægium was watered by two rivers, viz. the Phoenix and Meganites. The epithet is Ægientis. There is a coin in the cabinet of the king of Prussia, with the inscription ÆGIA, and the figure of a tortoise, which is the symbol of Peloponnesus, and leaves no doubt as to the place where it was struck.
