Purushamedha (or Naramedha) is a Śrauta ritual of human sacrifice, closely related to the Ashvamedha. The "Vajasaneyi Samhita-Sataphana Brahmana-Katyayana Srauta Sutra" sequence of White Yajur Veda texts contains the most details. Whether actual human sacrifice was taking place has been debated since Colebrooke brought the issue under attention in 1805. He regarded it as a symbolic ritual. Since there is no inscriptural or other record of Purushamedha ever being performed, some scholars suggest it was invented simply to round out sacrificial possibilities. Asko Parpola suggests actual human sacrifices are described in Vedic texts, while the "Brahmanas" show the practice diminishing. In "Shatapatha Brahmana" 13.6.2, an ethereal voice intervenes to halt the proceedings.
