Forms
ᾍδης (Hāídēs) m (genitive ᾍδου); first declension[1] Epic Ἀΐδης (Aḯdēs), genitive Ἀΐδαο or Ἀΐδεω, beside a shorter stem in the genitive Ἄϊδος and dative Ἄϊδι.[2][3] Doric Ἀΐδας, in tragic lyric.[2][3] Thessalian ἈϜίδας, in a 5th-century BC inscription.[4]
Etymology
In Beekes's view it is inherited from Proto-Indo-European *n̥wids (“unseen”), “the Unseen”, made of the negative prefix ἀ- (a-) and the root of εἶδον (eîdon, “I saw”).[2][1] The old root noun survives in the Homeric genitive Ἄϊδος (Áïdos); it was remodelled into an ā-stem, as Beekes argues for φυγή (phugḗ) beside φύγαδε (phúgade).[2][1] The initial vowel was short and was lengthened only for the metre, and the rough breathing of the Attic form is secondary, from contraction with the article ὁ (ho).[2][1][5]
Thieme instead derived it from Proto-Indo-European *sm̥-wid-, the gathering of the dead ancestors, comparing a Sanskrit compound of the same root, but Beekes rejects this because in Homer the word names the god rather than the place.[2][5] Wackernagel took the short vowel as secondary and connected Latin saevus (“fierce”), which Frisk finds less likely.[5] The New Pauly calls the etymology unclear.[6] The adjective ἀϊδής (aïdḗs, “invisible”) looks similar but is probably built on εἶδος (eîdos).[1]
The sense “unseen” was already proposed in antiquity, in Plato's Gorgias and Cratylus.[5][7]
Earliest recorded meaning
In Homer it is only the name of the god: in the Iliad Hades is the third of the brothers who divided the world, and his house is the world below.[3][4][8] The helmet of Hades, which made its wearer invisible, appears in the Iliad.[4] The Iliad also has the first use for the place of the dead.[3]
Semantic evolution
Attic said “in Hades'” and “to Hades'”, with the word for house understood.[3][4] Outside Attica the god's name had no rough breathing, and Homer also uses it for the underworld, whose gates the hound Cerberus guards.[6] After Homer it also meant death and the grave: Pindar speaks of receiving Hades, and Aeschylus of a death at sea.[3][4] Heraclitus identified Hades with Dionysus.[4] The genitive with a noun meant “hellish” or “deadly”, as in Aeschylus' “mother of Hades” for Clytemnestra and Euripides' “cook of Hades” for the Cyclops.[3][4]
The Septuagint uses it to render the Hebrew Sheol, and the New Testament for the place of the dead and of punishment, as in the “keys of death and of Hades”.[4][7] Astrologers called the region below the horoscope the gate of Hades.[3][4] It was borrowed as Latin Hādēs and Old Church Slavonic адъ (adŭ).[1] Modern Greek Άδης (Ádis) is the underworld of myth and of Christian teaching, and its king.[9]
