Achilles it was a great warrior of greek mythology, character of the "War of Troy", narrated by the Greek epic poet Homer, in the classic of the universal literature "Iliad", in the 9th century BC. Ç.
Achilles was the son of Peleus and Thetis and for him to become immortal, his mother plunged him into the river Stipe, holding him by the heels, which thus became the only vulnerable part of his body.
THE Homer's Iliad narrates Achilles' deeds, in the Trojan War, to rescue Helen, daughter of Pindar, king of Sparta, an incredibly beautiful woman, envied by the goddesses of Olympus themselves. Monarchs and princes came to visit her and never left without asking her to marry him. Helena opted for Menelaus, who shortly afterwards, with the death of Pindar, became king of Sparta.
During Menelaus' absence, the prince of Troy, Paris, son of King Priam, visited the Spartan court and fell hopelessly in love with Helen. He resolved to kidnap her, and thus provided the main reason for the "Trojan War".
A powerful expedition, featuring warriors, heroes and demigods like Achilles and Ulysses, under the protection of the gods, he vows to conquer Priam's palace and crosses the Aegean Sea, because Troy was located on the peninsula now occupied by the Turkey.
After many years of fighting and bravery in front of battles, Achilles was hit by a poisoned arrow hurled by Paris, who hit his heel, which according to mythology was a vulnerable part of him.
The popular expression “Achilles' heel” is used today to represent the weak and vulnerable point of something or someone.
