The most prominent of the Hyades is Aldebaran, the eye of the bull. At best, seven of the Hyades are visible to the naked eye. In early legend they were said to be seven nymphs placed by Jupiter in the sky. Later (Myth. 4.7) they became daughters of Atlas (a mythical giant said to support on his shoulders the pillars of the universe), and their number increased to twelve or fifteen. The name is probably derived from the Greek verb hyo, to rain; the V-shaped cluster of the Hyades, when rising simultaneously with the sun, was said to portend wet weather: hence the alternative name, and Spenser's epithet)

High time it seemed then for euery wight

Eftsoones long waxen torches weren light,

And safe commit to her soft fethered nest,

She soundly slept, and carefull thoughts did quite assoile.
