The first sign of the zodiac
Its symbol represents the head and horns of the ram. It is a symbol of offensive power — a weapon of the gods, hence an implement of the will. The Babylonians sacrificed rams during the period when the Sun occupied this sign, which occurs annually from March 21 to April 20.
Astrologically and astronomically, it is the first thirty-degree arc beginning at the point of the Spring Equinox.
It is the Leading (Cardinal) quality of the Fire element: positive, diurnal, dry, hot, fiery, choleric and violent.
