The Vedic poet beheld his head soaring aloft, but in the previous verse he has said, “I have beheld Horse, ... those impressions of the feet of thee”; and if these “impressions” were the stars which, on the Grecian sphere, marked the horse’s head, but, as I have contended, originally marked his hoof, then we shall understand how, associated with Soma, and identical with Trita by a mysterious act--_i.e._, at the season of the summer solstice, and when the moon was at its full in the constellation Aquarius, ancient astronomers imagined to themselves the horse Pegasus producing with his hoof the sweet exhilarating waters of the fountain Hippocrene. The date of this particular legend concerning the hoof of Pegasus I should be inclined to place at about 3000 B.C., when the solstitial colure was so closely marked by “those impressions of the feet” of the “swift horse sprung from the gods.” For the first imagining of the constellation I think that of 4000 B.C. is more probable (see Plate XXIV., Figs. 1, 2).
