30705 Idaios           Discovered 1977 Oct. 16 by C. J. van Houten and I. van Houten-Groeneveld on Palomar Schmidt plates taken by T. Gehrels.
Idaios was a herald of king Priam who tells Priam that Paris and Menelaos want to start a duel. Idaios is the younger son of the Hephaistos priest Dares. Idaios escaped Diomedes with the help of the god Hephaistos, because the god did not want his priest to lose both his sons.
