Apollo (uh-POL-oh). Roman name also Apollo. See The Olympians for more information and another picture. Apollo was the god of prophesy, music and healing. Like most of his fellow Olympians, Apollo did not hesitate to intervene in human affairs. It was he who brought about the demise of the mighty Achilles. Of all the heroes besieging the city of Troy in the Trojan War, Achilles was the best fighter by far. He had easily defeated the Trojan captain Hector in single combat. But Apollo helped Hector's brother Paris slay Achilles with an arrow.
