Forms

Οὐρᾰνός (Ouranós) m (genitive Οὐρᾰνοῦ); second declension[1]

Etymology

It is the common noun from Ancient Greek οὐρανός (ouranós, “sky, heaven”) used as the name of the sky personified.[1][2] Its Doric and Boeotian form is Ὠρανός (Ōranós).[1]

The origin of the common noun is disputed.[2][1] Beekes takes the Aeolic forms ὤρανος (ṓranos) and ὄρανος (óranos) to point to an older *ϝορσανός (*worsanós), perhaps an enlargement of a noun meaning “rain”, the word seen in Sanskrit वर्ष (varṣá, “rain”), so that the sky would be the “rainmaker”.[2][1] Others connect it with the root of वर्ष्मन् (varṣman, “height”) and Lithuanian viršùs (“top”), which Beekes considers weaker in both form and meaning.[2][1] He rejects the old comparison with the Vedic god वरुण (Váruṇa) outright, and Babiniotis also finds it formally impossible.[2][3] The suffix ⟨-αν-⟩ is hard to explain as an old Indo-European formation, so a Pre-Greek origin has also been suggested.[2][1] Aristotle derived the word from ὅρος (hóros, “limit”) and ἄνω (ánō, “up”), a folk etymology.[1][3]

Earliest recorded meaning

In the Iliad Ouranos is invoked as a witness to an oath, and Hesiod's Theogony makes him the son of Gaia, born of her alone so that he might cover her and give the gods a seat.[4][5] The earliest texts in the GLAUx corpus that name him are the Homeric Hymns.[6]

Semantic evolution

In Hesiod Ouranos is the husband of Gaia and father of the Titans (Titán), the Cyclopes and the Hundred-Handers.[5][7] He hid his children in the earth, and Gaia persuaded Κρόνος (Krónos) to castrate him with a sickle.[5][7] Erinyes, Giants and Nymphs sprang from the blood, and Ἀφροδίτη (Aphrodítē) from the foam around the severed parts.[5][7] The New Pauly traces this succession myth, Ouranos – Kronos – Zeus, to Near Eastern models, among them Hurrian and Hittite texts in which the sky god Anu corresponds to him.[5] Aristophanes makes Ouranos a child of Chaos and Eros.[4] The Latin equivalent of the god was Caelus, and the Greek name was taken into Latin as Uranus.[7][5]

As Uranus the name was given in 1800 to the planet discovered by William Herschel in 1781.[8] Modern Greek Ουρανός (Ouranós) is used for the planet, a learned borrowing of the New Latin name.[9]
