Pronunciation

  • 5th-century BC Attic: /dîː.os/[1]
  • 4th-century AD Koine: /ˈði.os/[1]
  • 10th-century Byzantine: /ˈði.os/[1]

Forms

δῖος (dîos) m (feminine δῖᾰ, neuter δῖον); first/second declension[1] Mycenaean di-wi-jo and di-u-jo, feminine di-wi-ja and di-u-ja.[2][3]

Etymology

It is inherited from Proto-Hellenic *díwiyos,[1] an old adjective of belonging formed from Proto-Indo-European *dyew- (“sky”), the root of Ζεύς (Zeús).[2][4][1] Beekes and Frisk reconstruct it as *diu-iHo-, identical with Sanskrit दिव्य (divyá, “heavenly”) and Latin dīus (“godlike”);[2][4] Wiktionary allows that the Greek and Indo-Iranian adjectives may have been formed separately from the same root.[1] The Mycenaean spellings Mycenaean Greek di-wi-jo and Mycenaean Greek di-u-jo support a form with /w/ before the suffix.[3][1] The development of the group /wy/ is disputed, which is why Sihler starts from the Proto-Hellenic form with /wiy/ rather than from a form *diwyós.[1]

The feminine δῖα (dîa) goes back to a separate form in short /a/ and was first a noun, “daughter of heaven, goddess”, as in the phrase “goddess among women”, on which “divine among goddesses” was modelled.[2][4] The adjective may stand for the genitive of the name of Zeus, “of Zeus”.[2][4]

The Etymologicum Magnum also derives it from the genitive of the name of Zeus, with a contraction of two vowels.[5]

Earliest recorded meaning

In Homer it is a frequent epithet: of goddesses, of the sky, the sea, the earth and the dawn, of heroes such as “godlike Achilles”, and even of the swineherd Eumaeus.[3][6][7] The sense “of Zeus” probably appears in the Iliad in the phrase δῖον γένος.[2][3]

Semantic evolution

The word belonged to epic and, later, to tragedy.[3] In Homer its sense is often vague and formulaic: “divine” of goddesses and of the powers of nature, “noble, excellent” of men, women, peoples, cities and horses.[3][6][8] The Etymologicum Magnum distinguishes three meanings in Homer: “glorious”, as of Achilles, “great” or “wondrous”, as of the sea, and “good”, as of the swineherd.[5] Hesychius explains it as “drawing one's descent from Zeus”, used loosely for “good”.[9]

The tragedians used it chiefly as the adjective of Zeus, “of Zeus, sent by Zeus”, as in Aeschylus' Prometheus, and Euripides speaks of the “fire of Zeus”, the thunderbolt.[6][3] Hellenistic poets such as Apollonius kept the epic use.[8] As Δῖος it was the name of a month in Macedonia, Thessaly and elsewhere.[2][3]

Timeline

  • Mycenaean period – The tablets have Mycenaean Greek di-wi-jo and Mycenaean Greek di-u-jo, and the genitive of a month name.[2][3]
  • 700s BC – The Iliad and the Odyssey use it as an epithet of goddesses, heroes, peoples and the powers of nature.[6][7][10]
  • Before the 6th century BC – Hesiod calls Phaethon a “divine spirit”.[11][6]
  • 6th–5th century BC – Aeschylus uses it as the adjective of Zeus.[6][3]
  • 5th century BC – Empedocles uses it of the sky, and Euripides speaks of the fire of Zeus.[6]
  • 3rd century BC – Apollonius of Rhodes uses it for goddesses and supernatural women.[8]

Meanings

Adjective

  1. Heavenly, divine, of goddesses and other supernatural beings; δῖα θεάων “divine among goddesses”.[6][8][11]
  2. Of the powers of nature, such as the sky, the sea, the earth and the dawn: divine, wondrous, perhaps “bright”.[6][8]
  3. Of men and women: noble, illustrious, excellent; also of peoples, cities and fine horses.[6][8]
  4. (tragedy) Of Ζεύς (Zeús), sent by Zeus.[6][3]

Usage notes

Δῖος was also the name of a month in Thessaly, Macedonia and other regions.[2][3] The poetic genitive Διός (Diós) is a different word, the name of the god himself.[2]
