It is the Roman writer and general Germanicus who in the first century AD. C., making a free translation of Arato’s Phainomena, associates Capricorn not with Pan but with a hybrid creature of a goat with a fish tail called Aegipán, Jupiter’s milk brother. Aegipán discovered a musical instrument —the conch shell— that he used in the fight of the gods against the giants, frightening them. As a reward, Zeus placed it among the stars as the constellation Capricorn. Germanicus also associated the sign with the Emperor Augustus.
