F. Max Müller,
India: What can it teach us?
“ The principal deity is here no doubt the bright sky itself, the old Dyaus, worshipped as we know by the Aryans before they broke up into separate people and languages, and surviving in Greece as Zeus, in Italy as Jupiter, Heaven-father, and among the Teutonic tribes as Tŷr and Tiu. In the Veda we saw him chiefly invoked in connection with the earth, as Dyâvâ-prithivî, Heaven and Earth. He is invoked by himself also, but he is a vanishing god, and his place is taken in most of the Vedic poems by the younger and more active god, Indra. ”
