*Diwōnā or *Diuōneh2, with a possible descendant in Zeus's consort Dione. A thematic echo occurs in the Vedic tradition as Indra's wife Indrānī displays a similar jealous and quarrelsome disposition under provocation. A second descendant may be found in Dia, a mortal said to unite with Zeus in a Greek myth. The story leads ultimately to the birth of the Centaurs after the mating of Dia's husband Ixion with the phantom of Hera, the spouse of Zeus. Another reflex may be found in the Mycenaean Greek Diwia, possibly a feminine counterpart of Zeus attested in the second part of the 2nd millennium BC and which may have survived in the Pamphylian dialect of Asia Minor. The reconstruction is however only based upon the Greek—and to a lesser extent the Vedic—tradition, and it remains therefore not secured. If the female goddesses Hera, Juno, Frigg and Shakti share a common association with marriage and fertility, Mallory and Adams note however that "these functions are much too generic to support the supposition of a distinct PIE 'consort goddess' and many of the 'consorts' probably represent assimilations of earlier goddesses who may have had nothing to do with marriage." Evidence Cognates stemming either from the root *dyeu ("daylight, bright sky"), the epithet *Dyēus Ph2ter ("Father Sky"), the vṛddhi-derivative *deiwós ("celestial", a "god"), the derivative *diwyós ("divine"), or the back-formation (a "day") are among the most widely attested in Indo-European languages. PIE: *d(e)i-, 'to shine, be bright', PIE: *dyēus, the daylight-sky god, Indo-Iranian: *dyauš, Sanskrit: Dyáuṣ (द्यौष्), the god of Heaven, and dyú (द्यु), the common word for "heaven", Old Avestan: dyaoš (𐬛𐬫𐬀𐬊𐬱), "heaven", mentioned in a single verse of the Avesta; Young Avestan: diiaoš, "hell", as a result of the Zoroastrian religious reformation, Mycenaean Greek: di-we (𐀇𐀸 /diwei/), dative case of an otherwise scarcely attested name, Cypriot Syllabary: ti-wo, interpreted as pertaining to Zeus, and the possible genitive Diwoi. Greek: Zeus (Ζεύς), the god of the Sky; also Boeotian Lac., Corinth., Rhod. dialects: Deús (Δεύς), Italic: (), Old Latin: Dioue or loue, Latin: Jove (Iove), the god of the Sky; and Diūs (Fidius), the god of oaths, Oscan: Diúvei (Διουϝει), genitive singular, Umbrian: Di or Dei (Grabouie/Graboue), attested in the Iguvine Tablets, Paelignian: Ioviois (Pvclois) and Ioveis (Pvcles), interpreted as a calque of the Greek theonym Diós-kouroi, Anatolian: *diéu-, *diu-, a "god", Hittite: šīuš (𒅆𒍑), a "god" or the Sun-God; a deity named Šiušummiš
