These bits of saga prove, as effectually as is possible in a case like this, that Indra was originally a warrior-king or chieftain who was deified, perhaps by the priestly tribe of the Aṅgirasas, who claim in some of the hymns to have aided him in his fight with Vṛitra, and that he thus rose to the first rank in the pantheon, gathering round himself a great cycle of heroic legend based upon those traditions, and only secondarily and by artificial invention becoming associated with the control of the rain and the daylight. The name Aśvinā means "The Two Horsemen"; what their other name, Nāsatyā, signifies nobody has satisfactorily explained. But even with the name Aśvinā there is a difficulty. They are described usually as riding together in a chariot which is sometimes said to be drawn by horses, and this would suit their name; but more often the poets say that their chariot is drawn by birds, such as eagles or swans, and sometimes even by a buffalo or buffaloes, or by an ass. I do not see how we can escape from this difficulty except by supposing that popular imagination in regard to this matter varied from very early times, but preferred to think of them as having horses. At any rate they are very ancient gods, for the people of Iran also have traditions about them, and in the far-away land of the Mitanni, in the north of Mesopotamia, they are invoked together with Indra, Mitra, and Varuṇa to sanction treaties. In India the Aryans keep them very busy, for they are more than anything else gods of help. Thrice every day and thrice every night they sally forth on their patrols through earth and heaven, in order to aid the distressed[12]: and the poets tell us the names of many persons whom they have relieved, such as old Chyavāna, whom they restored to youth and love, Bhujyu, whom they rescued from drowning in the ocean, Atri, whom they saved from a fiery pit, Viśpalā, to whom when her leg had been cut off they gave one of iron, and Ghōshā, to whom they brought a husband. Many other helpful acts are ascribed to them, and it is very likely that at least some of these stories are more or less true. Another legend relates that they jointly wedded Sūryā, the daughter of the Sun-god, who chose them from amongst the other gods.[13] [Footnote 12: Cf. _Ved. Studien_, ii. p. 31, RV.
