Mythology

Despite being faint, Capricornus has one of the oldest mythologies, as the representation of a hybrid goat and fish has been synonymous since the Middle Bronze Age. This started with the Babylonians.

Greek mythology sometimes identifies Capricornus as Amalthea, the goat that suckled the infant Zeus after his mother, Rhea, saved him from being devoured by his father, Cronos. Amalthea’s broken horn was transformed into the cornucopia or “horn of plenty”.

Capricornus is also sometimes identified as Pan, the god with a goat’s horns and legs, who saved himself from the monster Typhon by giving himself a fish’s tail and diving into a river.

History

The first depictions of the constellation was from around the 21st century BCE, but was explicitly recorded in the Babylonian star catalogues before 1000 BCE.

In September 1846, Johann Galle discovered the planet Neptune in what was the constellation Capricornus.
