Clement of Llanthony

Works Clement wrote a number of theological works, some of which still survive. Surviving works include commentaries on Acts of the Apostles and the Catholic Epistles, as well as works entitled De tribus in paenitentia consideranda and Unum ex quatuor.

The Unum, occasionally known as Concordia Quattuor Evangelistarum,

Most of Clement's works were derivative and did not contain much that was original thought. Instead, they comment on other works. Clement's commentary on his gospel harmony appears to have mainly compiled older writers' writings and contains little of his own thoughts on the Gospels, although it appears that he did compile the Unum directly from the four gospels and not from previous harmonies.

Most of Clement's works that survive remain unpublished. The only exception is part of Unum, which was partly published as a doctoral thesis in 1984. Most of Clement's works survive in one or two copies. Two works, De sex and Unum, have multiple copies. De sex survives in 12 manuscripts and Unum survives in at least 42 manuscripts, although in varied forms. Most of the copies of Unum are in the British Isles.
