RHEGMA(Ῥῆγμα), the name of a lake or lagune formed by the river Cydnus in Cilicia, at its mouth, about 5 stadia below Tarsus; the inhabitants of this city used it as their port. (Strab. 14. p. 672; Stadiasm. Mar. Mag. § § 155, 156, where it is called Ῥηγμοί; It. Hieros. p. 579.) The two last authorities place the Rhegma 70 stadia from Tarsus, which may possibly refer to a particular point of it, as the Rhegma was very extensive.
