Achilles was offered the hand of Polyxena, daughter of Priam, the king of Troy, if in return he would raise the siege of Troy. This deal was, however, a plot to kill him. Achilles went to make a sacrifice to Apollo on Polyxena's request, and while kneeling at the altar, was shot by her brother Paris. Apollo guided the arrow to Achilles heel, his only vulnerable spot. Surprisingly, the scene appears to depict Achilles dying in battle, which is the less depicted version told by Homer.
