The "Brahmana"s (9th to 6th centuries BCE) are the oldest scriptures to mention a relationship between Ahalya and Indra in the ""subrahmanya" formula", a chant used by Vedic priests "at the beginning of a sacrifice to invite the main participants: Indra, the gods and the Brahmins" (priests). The "Jaiminiya Brahmana" and the "Sadvimsha Brahmana" from the Samaveda tradition, the "Shatapatha Brahmana" and the "Taittiriya Brahmana" from the Yajurveda tradition and two "Shrautasutra"s ("Latyayana" and "Drahyayana") invoke Indra, the "lover of Ahalya ... O Kaushika who calls himself Gautama". The Samaveda tradition identifies her as Maitreyi, who the commentator Sayana (died 1387) explains is "the daughter of [the god Mitra".
