迦旃延，又迦旃延子之略。
(迦旃延子) Kātyāyana; Mahākātyāyana; Mahākātyāyanīputra; one of the ten noted disciples of Śākyamuni. The foundation work of the Abhidharma philosophy; viz. the Abhidharma-jñāna-prasthāna-śāstra, has been attributed to him, but it is by an author of the same name 300 to 500 years later. Other forms are 迦多衍那; 迦多衍尼子(or 迦多演尼子); 迦底耶夜那; 迦氈延 (尼子). There are others of the same name; e. g. the seventh of the ten non-Buddhist philosophers, perhaps Kakuda Kātyāyana, associated with mathematics, but spoken of as 'a violent adversary of Śākyamuni.' M. W.
