A river-god, is described as the son of Oceanus and Tethys, and as the husband of Metope, by whom he became the father of Hecabe. (Hes. Theog. 344 ; Apollod. iii. 12. § 5.) The river Sangarius (in Phrygia) itself is said to have derived its name from one Sangas, who had offended Rhea, and was punished by her by being changed into water. (Schol. ad Apollon. Rhod. ii. 722.)
