(Δύμας), a son of Aegimius, and brother of Pamphylus and Hyllus. The three tribes into which each Doric state was divided, derived their names from these three brothers, and were called accordingly Hylleis, Dymanes, and Pamphyli. Dymas and Pamphylus were believed to have lived from the time of Heracles until the conquest of Peloponnesus, when both fell. (Apollod 2.8.3; Schol. ad Pind. Pyth. 51.121, where the third brother is called Dorus; Paus. 7.16.3.)
