Atharvan

Atharvan (अथर्वन्, atharvan-; an n-stem with nominative singular अथर्वा atharvā) was a legendary Vedic sage (rishi) of Hinduism who along with Angiras is supposed to have authored ("heard") the Atharvaveda. He is also said to have first instituted the fire-sacrifice or yagna. Sometimes he is also reckoned among the seven seers or Saptarishi. His clan is known as the Atharvanas. Atharvan married Chitti, daughter of Kardama rishi, and had a great sage Dadhichi as a son. He was referred to as a member of the Bhrigu clan.
