Gryne'us
(Γρύνειος), a surname of Apollo, under which he had a temple, an ancient oracle, and a beautiful grove near the town of Grynion, Gryna, or Grynus in Aeolis in Asia Minor. (Paus. 1.21.9; Serv. ad Virg. Eclog. 6.72; Athen. 4.149; Steph. Byz. s. v. Γρύνοι.) Under the similar, if not the same name, Γρυνεύς, Apollo was worshipped in the Hecatonnesi. (Strab. xiii. p.618.) Ovid (Ov. Met. 12.260) mentions a centaur of the name of Gryneus. [L.S]
