The name given to the porisāda (cannibal) in the Mahāsutasoma Jātaka. Before becoming man-eater he was the king of Benares, and was later weaned from his evil habit by the Bodhisatta Sutasoma. He is identified with Angulimāla (J.v.pp.503f, 511).
Buddhaghosa (DA.ii.483) explains the name ("Spot=foot") as being given because of a wound he once received, which healed, leaving a scar like a piece of well-grained timber (cittadārusadiso). This refers to the flight of the porisāda from his pursuers, when he trod on an acacia stake (khānu) which pierced his foot (J.v.472).
According to Buddhaghosa, the cannibal in the Jayaddisa Jātaka was also called Kammāsa or Kammāsapāda. (DA.ii.483. See also Watanabe's article, "The Story of Kalmāsapāda and its Evolution in Indian Literature." J.P.T.S.1909, pp.236ff).
The place where the porisāda was tamed was called Kammāsadamma.
