Greek mythology
During the wedding of Pirithous and Hippodamia, the Centaurs got drunk and tried to assault and rape the invited women. Aphidas was sleeping on a bear-skin rug with a cup in his unconscious hand.
During the battle between the Lapitas and the Centaurs that followed the wedding, the Lapith Phorbas killed Aphidas with a thrown spear while he slept.
