|First appearance:||The Trojan Horse|
In Greek mythology, the Trojan War was waged against the city of Troy by the Achaeans (Greeks) after Paris of Troy left the city with Helen who was married to Menelaus king of Sparta. The war is one of the most important events in Greek mythology and has been narrated through many works of Greek literature, most notably through Homer's Iliad and the Odyssey. The Iliad relates a part of the last year of the siege of Troy; the Odyssey describes Odysseus's journey home.
The war originated from a quarrel between the goddesses Athena, Hera, and Aphrodite, after Eris, the goddess of strife and discord, gave them a golden apple, sometimes known as the Apple of Discord, marked "for the fairest".
Zeus sent the goddesses to Paris, who judged that Aphrodite, as the "fairest", should receive the apple. In exchange, Aphrodite made Helen, the most beautiful of all women and wife of Menelaus, fall in love with Paris, who took her to Troy. Agamemnon, king of Mycenae and the brother of Helen's husband Menelaus, led an expedition of Achaean troops to Troy and besieged the city for ten years because of Paris' insult. After the deaths of many heroes, including the Achaeans Achilles and Ajax, and the Trojans Hector and Paris, the city fell to the ruse of the Trojan Horse. The Achaeans slaughtered the Trojans (except for some of the women and children whom they kept or sold as slaves) and desecrated the temples, thus earning the gods' wrath. Few of the Achaeans returned safely to their homes and many founded colonies in distant shores.
Achilles was a hero of the Trojan War. Achilles’ most notable feat during the Trojan War was the slaying of the Trojan hero Hector outside the gates of Troy.
Although the death of Achilles is not completely agreed upon, other sources concur that he was killed near the end of the Trojan War by Paris, who shot him in the heel with an arrow. Later legends state that Achilles was invulnerable in all of his body except for his heel. Because of his death from a small wound in the heel, the term Achilles' heel has come to mean a person's point of weakness.
