Historians have now dug up enough facts to believe that something like the Trojan War may have really occurred. However, the story of how it began and what started it is part of Ancient Greek mythology. We learn most of what we know surrounding the myth of the Trojan War from the Ancient Greek epic Cypria by Stasinos of Cyprus who predated Homer.
In Cypria, we learn that quarrels amongst the gods led to the war, and it is the idea that the start of the war was rooted in the actions of the gods that makes the war a myth rather than a legend. According to myth, the war began with the story we refer to as "The Apple of Discord." The sea-goddess Thetis, Achilles' mother, married the hero Peleus, the father of Achilles. Unfortunately, Eris, the goddess of discord, was not invited to the wedding. Out of rage, Eris catered to the Greek pantheon's sense of vanity by throwing a golden apple onto the banquet table and saying that it belonged to the goddess that was the most beautiful. Naturally, Hera, Athena, and Aphrodite all challenged each other for the apple. Zeus decided the vain goddesses needed a mediator and chose Paris, the prince of Troy and the most handsome mortal man alive, to judge which goddess was the most beautiful. Each goddess decided to bribe him to turn the contest in the goddess's favor. Hera bribed him with power; Athena bribed him with wealth; and apparently Aphrodite offered the most tempting bribe--the most beautiful woman in the world as his bride. Paris, also guilty of a great sense of vanity, accepted Aphrodite's bribe and chose her as the most beautiful goddess. In return, Aphrodite gave Paris the promise of Helen as his wife, the world's most beautiful woman. The problem was that Helen was already married to King Menelaus, king of Sparta, also known as Mycenae and referred to as Achaea in the Iliad. But Helen's known marriage could not stop Paris's vanity, who soon sailed to Sparta to whisk Helen away from Menalaus. Naturally, when Paris refused to give Helen back, Menalaus declared war on Troy to win her back. Hence, according to legend, the Trojan War was started by the feelings of vanity, conceit, and arrogance that dominated the gods and goddesses of the Greek pantheon as well as Paris.
Throughout the Iliad, Homer paints Paris as a very vain, dishonest, and conceited man. We can especially see his vanity and conceit named when his older brother Hector upbraids him for shrinking from fighting with Menalaus in hand-to-hand combat in Book III:
Paris...evil-hearted Paris, fair to see, but woman-mad, and false of tongue, would that you had never been born, or that you had died unwed. Better so, than live to be disgraced and looked askance at.
Homer's interpretation of Paris shows us just how much Paris's vanity and conceit played a significant role in starting the war.
Greek myths and legends often involve gods and goddesses whom the Ancient Greeks worshipped. In most of the myths; the gods-goddesses’ affairs would generally influence the mortal world, greatly. Such a myth is the legend of the Trojan War. It lasted for ten years, and was brought about because of a quarrel among the gods.
Well, it all happenned like that:
The marriage of the great sea-goddess Thetis and Peleus was arranged, and all the gods and goddesses of Mount Olympus were invited except Eris – the goddess of discord(disagreement). Wherever she was, there was always trouble; quarrels broke out over the slightest thing and friendly gatherings and celebrations were ruined. Therefore, Eris was not invited to the wedding. Quite naturally, Eris became furious at being left out. So, she decided to spoil the wedding for everybody else. Out of revenge, she gate-crashed at the party and tossed out an apple, this read, “For the fairest”.
Immediately, the goddesses began to argue about who should take the apple. The quarrel raged on, furiously, between Hera, Athene and Aphrodite.
Atlast, Paris – the most handsome mortal living on the earth and the prince of Troy, was given responsibility of judging the goddess who deserved the apple.
Each of the goddesses tried to bribe Paris. Hera promised Paris to make him King of all Asia; Athene promised him that he would always be victorious in battle. Aphrodite promised him the love of the most beautiful woman in the world, a pretty attractive bribe, which Paris readily accepted and accordingly he gave the apple to Aphrodite.
The most beautiful woman in the world was Helen; but, unfortunately she was already married to King Menelaus. Nevertheless, Paris went to Greece and true to Aphrodite’s promise; he was able to carry off Helen with him to Troy.
King Menelaus was furious and the war began. Hera and Athene saw an opportunity to punish Paris for not awarding the golden apple to either of them. They helped the Greeks to attack and totally destroy the city of Troy in the famous war.
According to mythology, the Trojan War was caused by Eris, the goddess of discord, was excluded from a wedding. In revenge, she threw a golden apple onto a table during the banquet and stormed out of the celebration. Inscribed on the apple were the words "to the fairest." This inscription created a conflict between the goddesses Hera, Aphrodite, and Athena.
Zeus declared that Paris, a Trojan Prince, was the fairest human male and could judge which of the goddesses was the most beautiful and thus deserved the golden apple. Each of the goddesses offered Paris a gift; however, he accepted Aphrodite's gift. She promised him the most beautiful mortal woman, Helen. Unfortunately, Helen was already the wife of Menelaus, the king of Sparta. Menelaus gathered together all the previous suitors of Helen to come with him to Troy and defend her honor as well as reclaim the wealth stolen from him by Paris. His conquest of Troy marks the mythological beginning of the Trojan War.
