Tertuallian’s surviving writings are extensive. The Tertullain Project already has a large amount of information about his writings along with lists of available translations. That information will not be duplicated here.
Tertullian’s Apology is probably his most important work. A translation of that work not available at The Tertullian Project is available here:
- Terrot Reaveley Glover (translated ~1930)
- Tertullian and Marcus Minucius Felix, Volume 250 of the Loeb Classical Library (published 1930) — facsimile
