Aldebaran By: Katie Corbett Aldebaran in its constellation Aldebaran is from the constellation Taurus Taurus: The festivals honoring Apis Bull were when the Nile gently overflowed its banks. At this time in history, roughly around 4000 B.C., the Sun's position along the Zodiac on the first day of spring, or Vernal Equinox, was in that constellation we now recognize as Taurus, the Bull. So for many centuries Taurus was to be the first and most important constellation of the Zodiac. Some have suggested that Taurus may have been the first Zodiac constellation invented.
