Prometheus

Prometheus is the Titan of crafty counsel, foresight, and forethought. He is known for giving humans the gift of fire. He is the son of Iapetus and Clymene, the twin brother of Epimetheus and the brother-in-law of Pandora.

Early Life
Prometheus was the Titan of Forethought and Crafty Counsel, and apart of the second generation of Titans. He was born to Iapetus (the Titan of the West) and Clymene (an Oceanid). Prometheus was also the younger brother of Atlas (the Titan of Endurance), the twin brother of Epimetheus (the Titan of Afterthought), and the elder brother of Menoetius (the Titan of Rashness).

Unlike his brutal elder brother and careless twin brother, Prometheus was very sophisticated, and almost as intelligent as Cronus himself. During the "Golden Age", Prometheus made mankind out of clay, molding them after the Titans, but made them much smaller in size. Like most other Titans, Prometheus rarely visited his uncle Cronus on Mount Othrys, claiming to be too busy. Cronus, however, knew that the actual reason was Prometheus' secret fear of his uncle's might and infamous temper.

First Titanomachy
Unlike his brutal elder brother Atlas, Prometheus sided with the gods in the first Titanomachy because he could foresee that the Titans would lose. As a result, Prometheus was not imprisoned in Tartarus.

Prometheus' Punishment
Years later, because of his meddling nature, Prometheus stole fire for humans, which greatly boosted their progress as a species. He had already deceived Zeus prior to then by making him choose the worst part of an ox and giving the best one to humanity. These two actions, (more the fire than the ox) infuriated Zeus, and as a punishment, Zeus had Prometheus chained up on a mountain and had a huge and ferocious vulture peck out his liver every day, and as Prometheus' immortal liver regrew every night, the cycle could continue. This could only be evaded if someone broke the chains or if Prometheus told Zeus which of his fellow gods would overthrow him.

Freedom
During his journey to find the Garden of the Hesperides, Heracles arrived at the Caucasus, where he came across the imprisoned Prometheus; taking pity on him, Heracles shot down the eagle with one of his arrows and, with permission from his father, Zeus, set Prometheus free. Grateful for being freed, Prometheus advised Heracles on how to retrieve the apples; he was not to try to take them himself, but should instead approach Atlas and offered to take his burden while Atlas went to retrieve the apples.

Prophecy of Thetis
Prometheus later revealed to Zeus that the Nereid Thetis, were she to ever conceive, would give birth to a son more powerful than his father. Zeus hesitated before ending his relationship with Thetis, and had her marry the mortal hero Peleus instead. As a result, the Nereid gave birth to the great demigod hero Achilles.

Though initially thought of as such, Achilles turned out not to be the prophecy child, as Thetis later gave birth to Deicidia before being married off to Peleus.
