Kāṭhaka Brāhmaṇa
Kāṭhaka Brāhmaṇa was a Brāhmaṇa of Krishna Yajurveda, according to many of the Vedic Scholars and Vedic Pundits; however, it seems to have gone completely lost today. The followers of the Kāthaka tradition were specialists in the construction of Yāgasalas and Yajñakundas for agnicayana and it seems they were present mostly in the Northwest of India.
