Olynthus was a city in Macedonia, at the head of the Toronaic gulf, and north of the peninsula of Pallene. It was colonized by a people from Chalcis in Euboea, and commanded a large district called Chalcidice, in which there were thirty-two cities. Over all this tract the sway of Olynthus was considerable, and she had waged wars anciently with Athens and Sparta, and been formidable to Philip's predecessors on the throne of Macedon.
