Brillian rich yellow, no companion noted, one of the primary stars of the Hyades

A bright star with a distant telescopic companion, in the Bull's nostril. A 3½, fine yellow; B 11, pale blue, preceded by another small star in the sp quadrant.

This is Hyadum primus, or the leader of the Hyades, which, as the name implies, was esteemed a showery group; whence the pluviasque Hyadas of Virgil, and the moist daughters of Spenser. The family of Atlas was mentioned at η Tauri, but the Hyades were considered to be another batch of his daughters; though some, to lessen his burthen, dubbed them the Dodonides, or nurses of Bacchus.

The ancients were not agreed as to their number, for while Thales merely reckoned the two eyes, α and ε, Euripides counted three, and Hesiod five. Though the identity of this star must be pretty well established, it may be stated, that it lies about one-third of the distance from the Pleiades to the cluster in Orion's sword. But we learn from the poetaster that this direction is almost needless; for
Among those gorgeous hosts aloft
so gloriously shown,
The Hyades, and Pleiades,
to all who seek are known.
Pliny gives the name Palilicium to the Hyades, while others have made it proper to Aldebaran, because they rose heretofore at Rome, on the feast day of Pales; and Ovid lumps them together as Sidus Hyantis. The group was also called Y-psilon—the Pythagorean symbol of human life—from its shape; and from thence the Roman V, α and ε being the extremes, and γ the angular point.

From a notion, either that the same letter resembles a pig's jaws, or that Aldebaran with the Hyades were like a sow with her litter, the Latins designated them Suculæ. Cicero, however, thinks the name a corruption, from having mistaken the Greek word νεs, pigs, for νειν, to rain. It must not be forgotten that γ Tauri has a very appreciable proper motion in the awful void, the amount of which is thus severally given:
