Seven Deadly Sin: Lust
A more widely accepted account of their origin, they are descendants of Ixion, the son of Ares, God of War and King of the Lapiths, a people who lived in Thessaly, Northern Greece.
They were always involved in brawls and battles being legacy of Ares. Often Zeus would send the Centaurs to punish gods and humans who had offended him.
When Pirithous, a son of Ixion, married Hippodamia, he invited the centaurs because they were her kinsmen. But the centaurs could not handle wine. They made themselves drunk by drinking without moderation, and when the bride was brought in, they attempted to rape her and rest of the Lapith women. The strife among these cousins is a metaphor for the conflict between the lower appetites and civilized behavior in humankind. Theseus, a hero and founder of cities, who happened to be present, threw the balance in favor of the right order of things, and assisted Pirithous. The centaurs were driven off or destroyed. Their habitat now are lands like valleys, prairies, etc.
