161989 Cacus           Discovered 1978 Feb. 8 by H.-E. Schuster at the European Southern Observatory.
The fire-breathing monster Cacus, son of Vulcan, stole cattle Hercules had acquired as his tenth labor. Although Cacus tried to make it appear that the cattle had gone in the opposite direction, Hercules found them and strangled Cacus, erecting an altar at the spot that later became the Forum Boarium, the Rome cattle market.
