Agneyi (sans. आग्नेयी, IAST Āgneyī, 'Daughter of the Fire God') is mentioned in the Harivamsha and the Vishnu Purana as the wife of Ūru (a descendant of Angiras) and the mother of the kings Anga, Sumanas, Khyaati, Kratu and Sibi (Harivamsha includes another son, Gaya). Her father Agni is the Hindu God of Fire and has been revered and worshipped throughout the Indian subcontinent right from Vedic times to the modern era.
The masculine construction of the word, Āgneya, has been used as a generic adjective meaning flammable, fiery, consecrated to Agni, ruled by Agni etc. It has also been used as a proper noun epithet of the Agni Purana, the Āgneya Astra, and the cardinal direction of the South East (of which Agni is the Dikpala). The feminine construction Āgneyī is used only as proper noun.
Claims of worship
It is claimed that Āgneyī is known in ancient Vedic literature as Āgneyā where she is defined as a divine and powerful Goddess. Her mother is credited to be a consort of Agni interchangeably known as Svaha and Agnāyī (meaning, "Wife of Agni").
It is also claimed that the masculine epithet Āgneya used to signify the Southeastern cardinal direction actually refers to the Goddess Āgneyā. Likewise, she is also said to be the Shakti of the Āgneya Astra.
