134419 Hippothous           Discovered 1998 June 28 by E. W. Elst at the European Southern Observatory.
Hippothous, one of the sons of King Priam, was cursed together with his brothers by their angry father, as being disgraceful, prancing masters of the dance floor, who steal lambs and goats from their own people, because Hektor had been killed instead of them.
