BRIHASPATI, or Brahmanaspati ("god of strength"), a deity of importance in early Hindu mythology. In the Rigveda he is represented as the god of prayer, aiding Indra in his conquest of the cloud-demon, and at times appears to be identified with Agni, god of fire. He is the offspring of Heaven and Earth, the two worlds; is the inspirer of prayer and the guide and protector of the pious. He is pictured as having seven mouths, a hundred wings and horns and is armed with bow and arrows and an axe. He rides in a chariot drawn by red horses. In the later scriptures he is represented as a Rishi or seer.
