One cannot regard hymns addressed to Mitra-Varuna and S[=u]rya (with other gods) as primarily intended for S[=u]rya, who in these hymns is looked upon as the subject of Mitra and Varuna, as in VII.

62; or as the "eye" of the two other gods, and 'like Savitar' in VII.63.So in VII.66.

14-16, a mere fragment of a hymn is devoted exclusively to S[=u]rya as "lord of all that stands and goes." But in these hymns there are some very interesting touches.

Thus in VII.60.1, the sun does not make sinless, but he announces to Mitra and Varuna that the mortal is sinless.

There are no other hymns than these addressed to S[=u]rya, save those in the first and tenth books, of which nine stanzas of I.
50 (see above) may be reckoned early, while I.115, where the sun is the soul of the universe, and at the same time the eye of Mitra-Varuna, is probably late; and I.163 is certainly so, wherein the sun is identified with Yama, Trita, etc.; is 'like Varuna'; and is himself a steed, described as having three connections in the sky, three in the waters, three in the sea.
