The moist or fertilising god, occurs like Hyetius, as a surname of Zeus, as the sender of rain. (Hesych. s. v. huês.) Under the name of Hyetius, the god had an altar at Argos, and a statue in the grove of Trophonius, near Lebadeia. (Paus. ii. 19. § 7, ix. 39, S 3.) Hyes was also a surname of Dionysus, or rather of the Phrygian Sabazius, who was identified sometimes with Dionysus, and sometimes with Zeus. (Hesych. l.c.; Strab. p. 471.)
