37519 Amphios           Discovered 1977 Oct. 16 by C. J. van Houten and I. van Houten-Groeneveld on Palomar Schmidt plates taken by T. Gehrels.
Amphios, one of the allies of Priam, was killed by Ajax. Ajax killed Amphios mainly to get his beautiful armor. But a mountain of spears prevented Ajax from getting the armor.
