ÆGIUM, (anc. geog.) a town of Achaia Properia, five miles from the place where Helice stood, and famous for the council of the Acheans, which usually met there on account either of the dignity or commodious situation of the place. It was also famous for the worship of Οὐρανός Χιός, Conventional Jupiter, and of Panachæan Ceres. The territory of Ægium was watered by two rivers, viz. the Phœnix and Meganitas. The epithet is Ægientis. There is a coin in the cabinet of the king of Prussia, with the inscription ΑΙΓΙ, and the figure of a tortoise, which is the symbol of Peloponnesus, and leaves no doubt as to the place where it was struck.
