Capricornus represents a half goat half fish creature from ancient mythology.
Capricornus is based on extremely ancient mythology dating back some 4,000 years, it has always been associated with a mythological half goat half fish creature. In Greek mythology the constellation of Capricornus is associated with Pan, the god of the wild and music of the countryside. Pan was a faun, which were half human half goat creatures that personified and embodied the spirits of animals which dwelt in forests and other remote areas.
Pan was involved in the ‘War of the Gods’ which was fought between Zeus and his allies against the Titans, a group of powerful gods descended from Gaia and Uranus. Pan took the side of Zeus and during one of the battles he was attacked by the gigantic and destructive monster Typhon. Pan leaped into the river Nile to escape Typhon and in doing so transformed his goat legs into a fish’s tail, allowing himself to swim to safety. Zeus honored Pan by placing the image of him with the tail of a fish in the night sky.
