in Ancient Geography, a district of Macedonia, to the north of the Sinus Thermaicus, and east of the river Axios, which separates it from Bottaeis, and west of the river Strymon, (Pliny). Also a district of Mefopotamia, which took its name from that of Macedonia, running along the Euphrates, from Zeugma down to Thaplacus, extending a great way east, because Nisibis was reckoned to it.
