  Aldebaran - Alpha Tauri - Crystalinks
The star Aldebaran - Alpha Tauri - is the brightest star in the constellation Taurus.
Its name is derived from the Arabic word Al Dabaran, "follower", a reference to the way the star follows the Pleiades star cluster in its nightly journey across the sky.
Hebrews called Aldebaran God's Eye and Aleph, Akkadian Gis-da, Furrow of Heaven, Greek Omma Boos, Latin Oculus Tauri, early English the Bull's Eye; and Hindus Rohini the Red Deer - the name of the river in Nepal where the Buddha was born at the time of the May full moon, around 563 BCE.
