Auriga is one of the oldest constellations going back to the Babylonian times. It has always been associated with a charioteer.
The Babylonians, Greeks, Arabs, and Chinese have associated Auriga with a chariot.
According to one Greek myth, Hera had a child who was born lame. Disgusted, she threw him out of Heaven to Earth, where he became the famous lame smith, Hephaestus, who fashioned beautiful ornaments and armor for the gods. He is also the smith who came to Orion's rescue after Orion had been blinded. It is said that because he was lame he invented the chariot so that he might get around better.
Son of Helios (the sun god) and Hera (Zeus' wife).
