The Charioteer, a constellation situated between Perseus and Gemini. It is represented as a man holding a bridle in the right hand, and supporting a goat and kids on the left arm.

There is no satisfactory account of the mythology of this figure. It is said to have been the Horus of the Egyptians; among the Greeks, the human figure is by different writers called Erichthonius, Bellerophon, Hippolytus, .; while the goat is A mal the a, the foster-mother of Jupiter.
