Hyginus Fabulae, 33: CENTAURS.
When Hercules had come into the friendship of King Dexamenos and had deflowered his daughter Deianeira, and when he had pledged that he would take her to wife, he left. Then Eurytion, the centaur son of Ixion and Nubes (i.e. the Cloud, Nephale), sought Deianeira as his own wife. Her father feared retribution and promised that he would give him her hand. On the day determined for the wedding he came with his brothers to the wedding. Hercules intervened and murdered the centaur and took away the bride he had hoped for.
(3) Likewise, at another wedding, when Pirithous was marrying Hippodamia, daughter of Adrastus, the centaurs became drunk and tried to abduct the wives of the Lapith men; the centaurs murdered many of them, but they were beaten down by the Lapiths.

Hercules cum in hospitium ad Dexamenum regem uenisset, eiusque filiam Deianiram deuirginasset, fidemque dedisset se eam uxorem ducturum, post discessum eius Eurytion Ixionis et Nubis filius centaurus petit Deianiram uxorem. cuius pater uim timens pollicitus est se daturum. die constituto uenit cum fratribus ad nuptias. Hercules interuenit et centaurum interfecit, suam speratam abduxit. (3) Item aliis in nuptiis, Pirithous Hippodamiam Adrasti filiam cum uxorem duceret, uino pleni centauri conati sunt rapere uxores Lapithis; eos centauri multos interfecerunt, ab ipsis interierunt.
