Tertullian — Roman Author

Quintus Septimius Florens Tertullianus, anglicised as Tertullian, c. 155 – c. 240 AD, was a prolific early Christian author from Carthage in the Roman province of Africa. He is the first Christian author to produce an extensive corpus of Latin Christian literature. He also was a notable early Christian apologist and a polemicist against heresy, including contemporary Christian Gnosticism. Tertullian has been called "the father of Latin Christianity" and "the founder of Western theology.".. (wikipedia)
