The early sections of the Rigveda, which modern scholars place between 900 B.C. and 1500 B.C., describe the feats of a mythical being called Mātariśvan who brings fire, in the form of lightning, from afar, probably heaven, to the earth. After his arrival on earth, the fire disappears. Mātariśvan rediscovers the fire and brings it for safekeeping to the clan of Bhrigus who propagate the use of fire to all humanity. The later sections of the Rigveda identify Mātariśvan as Agni, the fire god, and in several verses there is discussion of the miracle of fire being produced by rubbing wooden sticks—the Sanskrit name for the wooden sticks used to create fire is Pramantha.
