2. One of the companions of Aeneas, from whom the town of Capua was said to have derived its name. (Verg. A. 10.145.) This Capys was a Trojan, and is mentioned by Virgil among those who were of opinion that the wooden horse should be thrown into the water. (Aen. 2.35.) Livy (4.37) states, that according to some traditions the town of Capua, which was previously called Vulturnum, derived its name from a Samnite chief of the name of Capys.
