Greek Hero: Achilles
The heroes of Greek myth are more than human, yet less than gods. However, using their supernatural powers for protection and war, they are and were praised as religious symbols, giving them a demigod-like status. Many of the prominent Greek heroes such as Achilles and Odysseus were involved in the famous Trojan War, in which the Achaeans (Greeks) waged war on the city of Troy after Paris of Troy took Helen from her husband Menelaus, king of Sparta.
In Homers Iliad (an epic Greek poem) Achilles was a great warrior, and was the main hero of the Trojan war. Achilles is the son of nymph Thetis and Peleus, king of the myrmidons. His mother, Thetis, is said to have dipped Achilles into the River Styx which runs through the underworld known as Hades, this action effectively made him immortal from birth...
During the Trojan War, which is part fact and part fiction, Achilles fought valiantly as he always did, however, upon storming the city of Troy he was shot in the heel by a poisoned arrow and died. Achilles' heel was the only vulnerable spot on his body due to the fact that this is where his mother had held him whilst dipping him in the River Styx. Today, the myth of Achilles lives on physically in the form of the Achilles tendon in your heel. However, the myth also lives on mentally as the "Achilles' heel" of something represents its weakness or vulnerability.
