Hylonome was a female centaur, wife of Cyllarus, and the couple enjoyed a legendary closeness, relating as equals. Hylonome was the only female centaur to be present at the centaurs’ battle with the Lapiths in Thessaly, at the wedding of their king. Cyllarus was slain in the battle, pierced by a javelin; Hylonome ran to embrace him, putting lips to lips in an effort to prevent his soul escaping, but he shortly died. In an excess of grief, Hylonome impaled herself on the javelin which had killed him, so she could join him in the underworld. The name Hylonome was given to a centaur body, one of a group of minor bodies orbiting between Jupiter and Neptune.
Astrologically, Hylonome represents excessive grief; loving, equality-based partnerships; and self-sacrifice or suicide.
