He was a prolific writer who wrote roughly 2,000 treatises in multiple branches of theology, including textual criticism, biblical exegesis and hermeneutics, homiletics, and spirituality. He was one of the most influential and controversial figures in early Christian theology, apologetics, and asceticism. He has been described by John Anthony McGuckin as "the greatest genius the early church ever produced". 184 – 254; died at about 70. Alive at the same time as Nagarjuna, Septimius Severus, Diophantus of Alexandria, Cyprian, and Plotinus. Wiki link
