[8] Various Angirasa sub-clans, including the Śunahotras, the Gautamas, and the Bhāradvājas composed Mandalas II, IV, and VI respectively.

[8][9] Other than crediting authorship, the Vedic texts mention sage Angiras in various roles such as a fire priest or a singer.

For example, the allegorical hymn 3.31 of the Rigveda calls him a singer: The most inspired one came, assuming a friendly attitude, The rock made ripe (its) fruit for the one who performs the kind deed, The young hero attained (his aim) with the youths, assuming a warlike attitude, And here right away, the singing Angiras appeared.

[11] In Buddhist Pali canonical texts such as Digha Nikaya, Tevijja Sutta describes a discussion between the Buddha and Vedic scholars of his time.

Further, the Vedic sage Angiras appears in medieval Hindu texts with contradictory roles as well as many different versions of his birth, marriage and biography.

He is credited as being the source of great number of Vedic Hymns and mantras and also believed to have introduced fire-worship along with sage Bhrigu.
