MIDAEIUM or MIDAIUM(Μιδάειον), a town in the NE. of Phrygia, on the little river Bathys, on the road from Dorylaeum to Pessinus, and belonging to the conventus of Synnada. (Steph. B. s. v.;Plin. Nat. 5.32. s. 41; Ptol. 5.2.22; Strab. 12. p. 576 ; Hierocl. p. 678, where it is wrongly called Μεδάϊον.) The town, as its name indicates, must have been built by one of the ancient kings of Phrygia, and has become celebrated in history from the fact that Sextus Pompeius, the son of Pompey the Great, was there taken prisoner by the generals of M. Antony, and afterwards put to death. (Dio Cass..) It has been supposed, with some probability, that the town of Mygdum, mentioned by Ammianus Marcellinus (Ammian. 26.7), is the same as Midaeium.
