ACHILLES was born the KING OF PELEUS of The MYRMIDONS of the of THESSALY and the sea nymphs THETIS. THETIS wanted to make her son immortal. she dipped ACHILLES into the RIVER STYX as a child( they also say he was dipped into a holy fire) he was immortal. he had one weakness during his dipping he was held by his left heel (Achilles) leaving that spot mortal.
Peleus was the son of Aeacus, King of Aegina and the father of the great Greek hero Achilles. Peleus' mother was Endeis. Peleus was banished along with his brother Telamon for murdering their step-brother Phocus. Eurytion of Phthia, uncle of Peleus and Telamon, received Peleus and gave him his daughter Antigone as wife along with a third of his land. Peleus accompanied Eurytion on the Calydonian boar hunt and killed him by accident. Peleus then fled to Iolcus.
Thetis was a minor goddess, a Nereid, who dwells in the sea. Zeus and Poseidon were rivals for her hand, but when they found out that her son was destined to be greater than his father, they let Peleus try for her. Thetis tried various transformations to avoid him, but he persisted and he finally married her.
Thetis knew that, if her son went to Troy, he would die an early death, so she sent him to the court of Lycomedes , in Scyros; there he was hidden, disguised as a young girl. Achilles' disguise was finally penetrated by Odysseus Achilles then went willingly with Odysseus to Troy, leading a host of his father's Myrmidons
At Troy, Achilles distinguished himself as an undefeatable warrior. Among his other exploits, he captured twenty-three towns in Trojan territory, including the town of Lyrnessos, where he took the woman Briseis as a war-prize. Later on Agamemnon , the leader of the Greeks, was forced by an oracle of Apollo to give up his own war-prize, the woman Chryseis , and took Briseis away from Achilles as compensation for his loss. Achilles became enraged and refused to fight for the Greeks any further. The war went badly, and the Greeks offered handsome reparations to their greatest warrior; Achilles still refused to fight in person, but he agreed to allow his friend Patroclus to fight in his place, wearing his armor
The next day Patroclus was killed and stripped of the armor by the Trojan hero Hector , who mistook him for Achilles.
Achilles was overwhelmed with grief for his friend and rage at Hector. His mother obtained magnificent new armor for him from Hephaestus , and he returned to the fighting and killed Hector. He desecrated the body, dragging it behind his chariot before the walls of Troy, and refused to allow it to receive funeral rites
When Priam , the king of Troy and Hector's father, came secretly into the Greek camp to plead for the body, Achilles finally relented; he received Priam graciously and allowed him to take the body away.
After the death of Hector, Achilles' days were numbered. He continued fighting heroically, killing many of the Trojans and their allies
clever Odysseus (some say with the aid of Athena) ordered a large wooden horse to be built. Its insides were to be hollow so that soldiers could hide within it.
Once the statue had been built by the artist Epeius, a number of the Greek warriors, along with Odysseus, climbed inside. The rest of the Greek fleet sailed away, so as to deceive the Trojans.
One man, Sinon, was left behind. When the Trojans came to marvel at the huge creation, Sinon pretended to be angry with the Greeks, stating that they had deserted him. He assured the Trojans that the wooden horse was safe and would bring luck to the Trojans.
Only two people, Laocoon and Cassandra, spoke out against the horse, but they were ignored. The Trojans celebrated what they thought was their victory, and dragged the wooden horse into Troy.
WHILE ACHILLES WAS FIGHTING BRAVELY SLAYING MANY TROJANS AND THEIR ALLIES. HECTOR’S BROTHER AND PRIAM SON THE PRINCE OF TROY PARIS AIDIED BY APOLLO WOUNDED ACHILLES IN THE HEEL WITH AN ARROW ACHILLES DIED OF THE WOUND
After his death, it was decided to award Achilles' divinely-wrought armor to the bravest of the Greeks. Odysseus and Ajax competed for the prize, with each man making a speech explaining why he deserved the honor; Odysseus won, and Ajax then went mad and committed suicide .
