from http://en.wikipedia.org/wiki/Battle_of_the_Centaurs_%28Michelangelo%29:

According to Condivi, the poet Poliziano suggested the specific subject to Michelangelo, and recounted the story to him.[4] The battle depicted takes place between the Lapiths and the Centaurs at the wedding feast of Pirithous.[1]Pirithous, king of the Lapith, had long clashed with the neighboring Centaurs. To mark his good intentions Pirithous invited the Centaurs to his wedding to Hippodamia, whose name ("Hippo," Ιππο, literally translates as "horse"), and may suggest some connection to them.[10]Some of the Centaurs, over-imbibed at the event, and when the bride was presented to greet the guests, she so aroused the intoxicated centaur Eurytion that he leapt up and attempted to carry her away.[11] This led not only to an immediate clash, but to a year-long war, before the defeated Centaurs were expelled from Thessaly to the northwest.
