Bienor is an Uranus orbit grazer and centaur. Bienor is asteroid #54598 or 2000 QC243 and Bienor is the third-largest of the confirmed centaurs. (2000 A.D. was obviously a yielding year for asteroid hunters.)

The mythological Bienor was a Centaur, who was killed by Theseus. This warrior, who became later the first king of Athens, had proven to be a deadly hazard to Centaurs, almost like Heracles later. Almost nobody seems to know the tale of Bienor. His name means “the strong” or “strong one” because he was known to be the strongest of the Centaurs and too proud to let anybody sit on his back. Mythology actually doesn’t tell that anybody did at any time ride on a Centaur, but maybe little children at Chiron’s school used to do that. It could then have been just too self-explaining for reporting it. Most times you get only told that Theseus slew Bienor either with a club or with bare hands. The lengthiest version of the tale, that I know, states that Theseus had just broken the elbow of another Centaur and was about to kill him, but then Bienor interfered and saved his comrade. Theseus changed his target, jumped on the back of Bienor, pulled Bienor’s head back, so that Theseus could punch him frontally in the face. Theseus broke Bienor’s skull and hit him repeatedly until Bienor was dead.

Astrologically centaurs tell us something about the interactions between living beings. There is much speculation about Bienor because most people know only a chunk of his tale. The lengthier version, that I’ve given here, should put everything clear. Bienor is about interventions. Bienor lets you take somebody else’s burden.
