Fire was of old the element of fiends. No doubt this was in part due to the fact that it also was a devouring element. Sacrifices were burnt; the demon visibly consumed them. But the great flame-demons represent chiefly the destructive and painful action of intense heat. They originate in regions of burning desert, of sunstroke, and drouth.
Agni, the Hindu god of fire, was adored in Vedic hymns as the twin of Indra.
‘Thy appearance is fair to behold, thou bright-faced Agni, when like gold thou shinest at hand; thy brightness comes like the lightning of heaven; thou showest splendour like the splendour of the bright sun.
‘Adorable and excellent Agni, emit the moving and graceful smoke.
‘The flames of Agni are luminous, powerful, fearful, and not to be trusted.
‘I extol the greatness of that showerer of rain, whom men celebrate as the slayer of Vritra: the Agni, Vaiswanara, slew the stealer of the waters.’
The slaying of Vritra, the monster, being the chief exploit of Indra, Agni could only share in it as being the flame that darted with Indra’s weapon, the disc (of the sun).
‘Thou (Agni) art laid hold off with difficulty, like the young of tortuously twining snakes, thou who art a consumer of many forests as a beast is of fodder.’
Petrifaction awaits all these glowing metaphors of early time. Verbal inspiration will make Agni a literally tortuous serpent and consuming fire. His smoke, called Kali (black), is now the name of Siva’s terrible bride.
Much is said in Vedic hymns of the method of producing the sacred flame symbolising Agni; namely, the rubbing together of two sticks. ‘He it is whom the two sticks have engendered, like a new-born babe.’ It is a curious coincidence that a similar phrase should describe ‘the devil on two sticks,’ who has come by way of Persia into European romance. Asmodeus was a lame demon, and his ‘two sticks’ as ‘Diable Boiteux’ are crutches; but his lameness may be referable to the attenuated extremities suggested by spires of flame—‘tortuously twining snakes,’—rather than to the rabbinical myth that he broke his leg on his way to meet Solomon. Benfey identified Asmodeus as Zend Aêshma-daêva, demon of lust. His goat-feet and fire-coal eyes are described by Le Sage, and the demon says he was lamed by falling from the air, like Vulcan, when contending with Pillardoc. It is not difficult to imagine how flame engendered by the rubbing of sticks might have attained personification as sensual passion, especially among Zoroastrians, who would detach from the adorable Fire all associations of evil. It would harmonise well with the Persian tendency to diabolise Indian gods, that they should note the lustful character occasionally ascribed to Agni in the Vedas. ‘Him alone, the ever-youthful Agni, men groom like a horse in the evening and at dawn; they bed him as a stranger in his couch; the light of Agni, the worshipped male, is lighted.’ Agni was the Indian ‘Brulefer’ or love-charmer, and patron of marriage; the fire-god Hephaistos was the husband of Aphrodite; the day of the Norse thunder-and-lightning god Thor (Thursday), is in Scandinavian regions considered the luckiest for marriages.
