Kephalaia (Koine Greek and ) is a genre of Manichaean literature represented mainly by two large papyrus codices containing Coptic translations from 5th-century Roman Egypt. The kephalaia are sometimes seen as the actual words or teachings of the prophet Mani, but are probably better viewed as later discourses and interpretations laid upon "an authoritative oral tradition" ostensibly going back to Mani and thus analogous to the Talmud in Judaism and the ḥadīth in Islam.
