The Commentaries on John and on Matthew are both embraced in several manuscripts. Of those on John, Mr. A. E. Brooke (Texts and Studies, vol. i. No. 4; The Fragments of Heracleon, pp. 1–30; “the mss. of Origen’s Commentaries on S. John”) enumerates eight or nine. The Munich ms. of the thirteenth century is the source of all the rest. Huet, the first editor (1668), used the Codex Regius (Paris) of the sixteenth century, which is in many passages mutilated and disfigured. The brothers Delarue (1733–1759) used the mss. Barberinus and Bodleianus, which are more complete, and Lommatzsch (1831) follows his predecessors. The present translations are from the text of Lommatzsch, which is in many places very defective.
