author of the Āśvalāyana-śrauta-sūtra, Vedic manual of sacrificial ceremonies composed for the use of the class of priests called hotar, or hotṛ, whose main function was to invoke the gods. Belonging to the “forest tradition” of hermits and wandering holy men rather than to that of the priesthood, Āśvalāyana is mentioned as a teacher as well as a sage in Vedic litanies and in the one text is invoked along with Indra and the “sons of Brahmā.” He is described as a student of Śaunaka, who composed many texts.
