The Iliad is an epic poem attributed to Homer about the Trojan War. It tells the story of how a battle between Agamemnon and Achilles started the war. Agamemnon was the leader of the Greek forces while Achilles was the greatest Greek warrior. Other major figures included Zeus, king of the gods, Apollo the god of prophecy, Poseidon the god of the sea, Aphrodite the goddess of love, Hector the leader of the Trojan forces, and Athena the goddess of wisdom. Helen's abduction by Paris sparked the war between the Greeks led by Menelaus and the Trojans.
