Agni (Fire) God has been worshipped by Hindus from the Vedic. Agni is one of the three supreme deities of the Rig Veda, viz., Agni, Vayu and Surya. These three Gods preside over earth, air and sky respectively.
In Rig Veda, largest number of hymns are addressed to Agni. Agni is the son of Angiras and the grandson of Sandila, one of the seven great sages. Vishnu Puran, however, claims that Agni is the eldest son of Brahma. His wife is Swaha and through his marriage he has three sons, Pavak, Pavman and Suchi.
In Hari Vans, Agni is clothed in black and has smoke as his standard and carries a flaming javelin. He has four hands and rides in a chariot drawn by red horses.
Agni Purana is said to have been recited by Agni himself to sage Vashist. It has portions on ritualistic and mystic methods of worship, the art of wars the laws of Hindus and glorification of Shiva.
