||Rain (hyô, hyetos)
HYAS was a daimon (spirit) of seasonal rains, brother of the Hyades (Starry Rain-Nymphs), and a son of the firmament-bearing Titan Atlas. As a young boy he was killed in the wilds by a lion. The gods afterwards set him amongst the stars as the constellation Aquarius, along with the lion Leo, and his five mourning sisters as the Hyades. Aquarius and Leo do not share the sky at the same time, one setting as the other rises.
He was probably identified with Hylas, the young lover of Herakles who was kidnapped by water nymphs (the Hyades?) when he was sent to fetch water.

HYAS (Huas). The name of the father and brother of the Hyades. (Hygin. Poet. Astr. ii. 21; Ov. Fast. v. 181; Eustath. ad Hom. p. 1155.) The father was married to Boeotia, and was looked upon as the ancestor of the ancient Hyantes. (Plin. H. N. iv. 12; comp. Müiller, Orchom. p. 124.) His son, or the brother of the Hyades, was killed in Libya by an animal, a serpent, a boar, or a lion. (Hygin. Fab. 192.)

Hesiod, Astronomy Fragment 2 (from Scholiast on Aratus 254) (Greek epic C8th or C7th B.C.) :
"But Zeus made them [the sisters of Hyas] into the stars which are called Hyades."
Pseudo-Hyginus, Fabulae 192 (trans. Grant) (Roman mythographer C2nd A.D.) :
"Atlas by Pleione or an Oceanid had twelve daughters, and a son, Hyas. The son was killed by a wild boar or a lion, and the sisters, grieving for him, died of this grief. The five of them first put among the stars have their place between the horns of the bull--Phaesyla, Ambrosia, Coronis, Eudora, Polyxo--and are called, from their brother’s name, Hyades."
Pseudo-Hyginus, Astronomica 2. 21 :
"The Pleiades (Many) were so named, according to Musaeaus, because fifteen daughters were born to Atlas and Aethra, daughter of Oceanus. Five of them are called Hyades, he shows, because their brother was Hyas, a youth dearly beloved by his sisters. When he was killed in a lion hunt, the five we have mentioned, given over to continual lamentation, are said to have perished. Because they grieved exceedingly at his death, they are called Hyades. The remaining ten brooded over the death of their sisters, and brought death on themselves; because so may experienced the same grief, they were called Pleiades. Alexander says they were called Hyades because they were daughters of Hyas and Boeotia, Pleiades, because born of Pleio, daughter of Oceanus, and Atlas."
Ovid, Fasti 5. 164 ff (trans.Boyle) (Roman poetry C1st B.C. to C1st A.D.) :
"When darkening twilight ushers in the night, the whole flock of Hyades is revealed. Taurus’ face gleams with seven rays of fire, which Greek sailors call Hyades from their rain-word. To some they were the nurses of Bacchus [Dionysos], to others granddaughters of Tethys and old Oceanus. Atlas did not shoulder the load of Olympus yet, when lovely, eye-catching Hyas was born. Oceanus’ daughter, Aethra, bore him and the Nymphae in timely births, but Hyas was born first. While his beard was fresh, stags trembled in terror before him, and the hare was welcome prey. But when years matured his manhood, he breavely closed with the shaggy lioness and the boar. He sought the lair and brood of the whelped lioness and was bloody prey to the Libyan beast. His mother sobbed for Hyas, his sad sisters sobbed and Atlas, whose neck would haul the world. The sisters surpassed both parents in pious love and won heaven. Their name is from Hyas."
