Orsinus
Orsinus a tributary of the Maeander, flowing in a north-western direction, and discharging itself into the main river a few miles below Antioch (Plin. Nat. 5.29). As some MSS. of Pliny have Mossynus, and as Hierocles (p. 665) and other ecclesiastical writers (Notit. Episc. Phryg. Pac. p. 27) speak of a town Mosyna in those parts, the river was probably called Mosynus. Its modern name is said to be Hagisik, that is the river described by Col. Leake (Asia Minor, p. 249) as descending from Gheira and Karajasu.
