What is "dyeus"

Dyēus (also *Dyēus Ph₂tḗr, alternatively spelled dyēws) is believed to have been the chief deity in the religious traditions of the prehistoric Proto-Indo-European societies. Part of a larger pantheon, he was the god of the daylight sky, and his position may have mirrored the position of the patriarch or monarch in society. In his aspect as a father god, his consort would have been , " earth mother".

This deity is not directly attested; rather, scholars have reconstructed this deity from the languages and cultures of later Indo-European peoples such as the Greeks, Latins, and Indo-Aryans. According to this scholarly reconstruction, Dyeus was addressed as Dyeu Phter, literally " sky father" or "shining father", as reflected in Latin Iūpiter, Diēspiter, possibly Dis Pater and deus pater, Greek Zeu pater, Sanskrit . As the pantheons of the individual mythologies related to the Proto-Indo-European religion evolved, attributes of Dyeus seem to have been redistributed to other deities. In Greek and Roman mythology, Dyeus remained the chief god; however, in Vedic mythology, the etymological continuant of Dyeus became a very abstract god, and his original attributes and dominance over other gods appear to have been transferred to gods such as Agni or Indra.
