In the Vamsa Brahmana of Vedic literature, Aupamanyava is listed as a Vedic teacher and sage. of the Sama Veda.
The patronymic Aupamanyava establishes him as a descendant of Upamanyu, while the name Kamboja suggests an association with the Kamboja kingdom of the (late Vedic) Mahajanapada period.
Vamsa Brahmana informs us that sage Anandaja had received the Vedic learning from sage Samba, the son of Sarkaraksa, as well as from Kamboja, the son or descendant of Upamanyu.
Vamsa Brahamana of the Sama Veda refers to one Rsi Madragara Shaungayani as the teacher of Aupamanyava Kamboja. As the name itself suggests, risi Madragara Shaungayani belonged to Madra tribe, i.e. the Uttaramadras.
Dr Jain also observes: "Kamboja Aupamanyava, pupil of Madragara, is mentioned in the Vamsa Brahmana. This points to a possible relationship of the Madras or more probably of the Uttaramasdras with the Kambojas, who probably had Indian as well as Iranian affinities".
Aupamanyava is repeatedly quoted as a grammarian by Yaska in his Nirukta, and also mentioned in respect of the Nisadas and the Panca-janah. Aupamanyava is also stated to have authored one Nighantu—a collection of Vedic words Pt Bhagva Datta points out that, Dr G. Opart has referred to one nirukta (etymology) whose authorship he attributes to a certain Upamanyu
Commenting on the Vamsa Brahmana list of Vedic teachers, Albrecht Weber writes: "One fact deserves to be especially noticed here, namely, that several of the teachers mentioned in the Vamsa Brahmana, by their very names, points us directly to the north-west of India, e.g. Kamboja Aupamanyava, Madaragara Saungayani, Sati Aushtrakshi, Salamkayana and Kauhala" . And commenting on the same list, R Morton Smith also writes: “The names Kamboja Aupamanyava, Sati Austraksi and Madragara Saungayani suggest a North-west connection for the main branch of Vamsa Brahmana.
