A god with a better defined and more recognisable department is Tvashtri, who is in a vague kind of way the counterpart of the Greek Hephaestus. He sharpens the axe of Brahmanaspiti, and forges the bolts of Indra. He also bestows offspring, is a kind of male Aphrodite, and is the shaper of all forms human and animal. Saranyu is his daughter. Professor Kuhn connects her with the storm-cloud, Mr. Max Müller with the dawn.* Her wedding in the form of a mare to Vivasvat in the guise of a horse has already been spoken of and discussed. Tvashtri's relations with Indra, as we have shown, are occasionally hostile; there is a blood-feud between them, as Indra slew Tvashtri's three-headed son, from whose blood sprang two partridges and a sparrow.** The Maruts are said to be gods of the tempest, of lightning, of wind and of rain. Their names, as usual, are tortured on various by the etymologists. Mr. Max Müller connects _Maruts_ with the roots _mar_, "to pound," and with the Roman war-god Mars. Others think the root is _mar_, "to shine". Benfey*** says "that the Maruts (their name being derived from _mar_, 'to die') are personfications of the souls of the departed". * Max Müller, _Lectures on Language_, ii. 530. ** Muir, v. 224, 233. *** Ibid., v. 147. Their numbers are variously estimated. They are the sons of Rudra and Prisni. Rudra as a bull, according to a tale told by Sayana, begat the Maruts on the earth, which took the shape of a cow. As in similar cases, we may suppose this either to be a survival or revival of a savage myth or a merely symbolical statement. There are traces of rivalry between Indra and the Maruts. It is beyond question that the Rishis regard them as elementary and mainly as storm-gods. Whether they were originally ghosts (like the Australian Mrarts, where the name tempts the wilder kind of etymologists), or whether they are personified winds, or, again, winds conceived as persons (which is not quite the same thing), it is difficult, and perhaps impossible, to determine.
