Mbh 3.220.1b

And the fire in whose honour oblations of clarified butter are enjoined to be made here at the Darsa and Paurnamasya sacrifices and who is known as Vishnu in this world, is (the third son of Bhanu) called Angiras, or Dhritiman. And the fire to whom with Indra, the Agrayana oblation is enjoined to be made is called the Agrayana fire. He is the (fourth) son of Bhanu. The fifth son of Bhanu is Agraha who is the source of the oblations which are daily made for the performance of the Chaturmasya (four-monthly) rites. And Stuva is the sixth son of Bhanu. Nisa was the name of another wife of that Manu who is known by the name of Bhanu. She gave birth to one daughter, the two Agnishomas, and also five other fire-gods. The resplendent fire-god who is honoured with the first oblations in company with the presiding deity of the clouds is called Vaiswanara. And that other fire who is called the lord of all the worlds is Viswapati, the second son of Manu. And the daughter of Manu is called Swistakrit, because by oblations unto her one acquires great merit. Though she was the daughter of Hiranyakasipu, she yet became his wife for her evil deeds. She is, however, one of the Prajapatis. And that other fire which has its seats in the vital airs of all creatures and animates their bodies, is called Sannihita. It is the cause of our perceptions of sound and form. That divine spirit whose course is marked with black and white stains, who is the supporter of fire, and who, though free from sin, is the accomplisher of desired karma, whom the wise regard as a great Rishi, is the fire Kapila, the propounder of the Yoga system called Sankhya. The fire through whom the elementary spirits always receive the offerings called Agra made by other creatures at the performance of all the peculiar rites in this world is called Agrani. And these other bright fires famous in the world, were created for the rectification of the Agnihotra rites when marred by any defects.
