Adda, also referenced in Latin as Adimantus, was one of Mani's earliest followers and an exegentical writer commenting on the Greek scriptures and Mani's psalms. The preliminary diffusion of Mani's revelation into the late Roman empire was advocated by his disciple Adda, which St. Augustine would have been familiar with from his time among them as an acolyte. This polemic by St. Augustine would help clarify both the Catholic position in response to Manichean claims, but also help to extinguish the religion amongst intellectual circles in the West. Moreover, the questions posed by Adda about challenges to thew Hebrew Scriptures by the Manicheans would be preserved here for posterity, even as the religion of Mani would totally disappear from the world's religious landscape.
