In European lore, Sapphire is linked to the Greek hero Prometheus, who introduced fire to mankind, against the will of the gods. For this brave deed he was chained to a mountain and every day an eagle came to eat his liver. After centuries, Prometheus was finally freed by another hero, Hercules. As the last of his 12 great labors, Hercules killed the eagle and petition Zeus to pardon Prometheus. The King of the Gods agreed, with one caveat. Prometheus would have to wear a ring forged from the mountain and his chain, a physical reminder of the consequence of ignoring the will of the gods. The chain was used to craft the ring itself, while a gemstone from the mountain was placed on top. This gem was a brilliant blue Sapphire, whose color is like the center of the hottest flames.
In the ancient Vedic texts, revered by followers of the Hindu faith, Blue Sapphires were the eyes of the demon god Vala. According to the story, Vala once took the form of a stone cave where stolen cows were hidden. Indra, the leader of the demigods, split Vala apart, killing him and freeing the cows. Vala’s body was scattered across the earth, and his various body parts were transformed into different gemstones. Yellow Sapphire is also mentioned in this story, and signifies the skin of Vala.
