“In Greek mythology, the Hyades were the five daughters of Atlas and half-sisters to the Pleiades. After the death of their brother, Hyas, the weeping sisters were transformed into a cluster of stars that was afterwards associated with rain.

As a naked-eye object, the Hyades cluster has been known since prehistoric times. It is mentioned by numerous Classical authors from Homer to Ovid.

In Book 18 of the Iliad the stars of the Hyades appear along with the Pleiades, Ursa Major, and Orion on the shield that the god Hephaistos made for Achilles.

In England the cluster was known as the “April Rainers” from an association with April showers, as recorded in the folk song “Green Grow the Rushes, O”.

The cluster was probably first catalogued by Giovanni Batista Hodierna in 1654, and it subsequently appeared in many star atlases of the 17th and 18th centuries.[13] However, Charles Messier did not include the Hyades in his 1781 catalog of deep sky objects.

It therefore lacks a Messier number, unlike many other, more distant open clusters – e.g., M44 (Praesepe), M45 (Pleiades), and M67.

In 1869, the astronomer R.A. Proctor observed that numerous stars at large distances from the Hyades share a similar motion through space.
In 1908, Lewis Boss reported almost 25 years of observations to support this premise, arguing for the existence of a co-moving group of stars that he called the Taurus Stream (now generally known as the Hyades Stream or Hyades Supercluster). Boss published a chart that traced the scattered stars’ movements back to a common point of convergence.”*
