We remember the numerous hymns of the Veda which celebrate the benefits conferred upon men by Agni, the spirit of fire, who is born from the double wood, and descends to earth in the lightning from the water-bed of the storm-cloud; the glow of this bright youth preserves men from beasts of prey, from murderers and evil spirits, helps the gods to victory, and contends in battle in the van; at the same time a royal house-lord and priest, Agni is in the Veda the upholder of the religious worship, the mediator between heaven and earth (IV. 40). The Avesta is filled with similar conceptions, though less poetical in form. Here the power as victorious of fire against the demon takes the first place. We saw that Mithra's chariot carried the kindled fire. "The sacred, strong fire" is invoked as a "warrior," as a "protector," as a slayer of the evil spirits, as the giver of good. To whatever side, we are told in the book of the law, the wind carries the smoke of the fire, it comes back thence as a slayer of thousands. "Happy is the man," we are told in an invocation, "to whom thou comest in strength, O Fire, son of Auramazda, more friendly than the friendliest, worthy beyond others of supplication. O Fire, we approach thee with perfect purity, with a good spirit; mayest thou come down to us bringing help."[190] He who uses dry selected wood for the fire, him the fire blesses, saying: "May herds of cattle gather round thee, and abundance of men; may all things succeed according to the wish of thy soul. Live out thy life happily to the full extent to which thou wilt live. The fire speaks with all those for whom it shines the whole night through, and cooks food; from all it demands good nourishment. The fire looks on the hands of all who come; what does the friend bring to the friend, he who approaches to him who sits alone?[191]" The Gathas of the Avesta also speak of the pieces of wood for friction, out of which springs the fire that shows the way;[192] and in another passage we hear of the fire Urvazista which dwells in wood. The Avesta distinguishes between the fire Çpenista, _i.e._ the house-lord, the hearth-fire (it is the same name that is given to the hearth-fire in India), the most victorious fire Verethraghna, which slays all the demons, and by which, according to the custom of the Parsees, the fires of the hearth must be renewed year by year, and the fire of lightning, which is called Vazista. This last, which comes down direct from heaven, is the "most sacred of all fires, which slays the demon Çpenjaghra."[193] In the Avesta the priests are called Athravas, a name which, no doubt, goes back to the worship of fire (_athar_); among the Indians Atharvan entices the fire from the wood, and together with Manu and Dadhyanch kindles the first sacrificial fire; the fourth Veda is called after him (IV. 280). In the Avesta also the red glowing fires, which gleamed on the earth in the days of King Yima, are repeatedly mentioned (p.
