Nicolas Poussin: "The Infant Bacchus Entrusted to the Nymphs of Nysa; The Death of Echo and Narcissus" (1657). The painting shows Mercury (in Greek, Hermes) delivering the newly born baby Bacchus (in Greek, Dionysus) to the nymphs of Nysa. The Hyades were also called the nymphs of Nysa because they lived on Mount Nysa.

Hyades

For the ancient Greeks, the Hyades were daughters of Pleione and Atlas, a giant who carried the heavens on his shoulders. The Hyades had several sisters, such as the Pleiades and the Hesperides. They were very attached to their brother Hyas. One day, while Hyas was hunting, he was killed by a lion. The Hyades were so overcome with grief they committed suicide.

Zeus changed them into a cluster of stars and placed them in the constellation Taurus the Bull. Zeus was grateful to them because they nursed his son the god Dionysus. One of the Hyades, Aldebaran, is the brightest star and represents the Bull's eye. The other Hyades are in a V-shape, forming the horns and the nose of the bull.

Because the Hyades appear during rainy seasons, the Greeks believed them to be messengers of spring rain showers and autumn storms. Their name means in Greek "to rain." The rain was believed to represent their tears of grief for their brother Hyas.
