I don’t believe that the text of ancient literature can be in copyright. Publishers claim otherwise, but as far as I know these claims have not been tested in court. The idea is a shameful abuse of copyright law; like claiming copyright of Shakespear. Unfortunately once money is involved, it seems more prudent for a little chap like me to pay them than pay lawyers.
My remaining copyright issue concerns the fragments from Jerome’s Commentary on Matthew, and those from Anastasius of Sinai, Quaestiones et responsiones.
The critical edition of the Jerome is Hieronymus, Commentariorum in Matheum libri IV. Corpus Christianorum, Series Latina 77 Turnhout, Brepols, 1969. The extracts printed by Mai are about 500 words in total.
The critical edition of the Anastasius is Anastasii Sinaitae Quaestiones et responsiones, Corpus Christianorum, Series Graeca 59. Ed. Marcel Richard; Joseph A Munitiz. Turnhout : Brepols, 2006. There are three extracts, two from Q.153 and one from Q.148, in total 581 words.
Both are owned by Brepols, the big Belgian publisher. It is a great pity that the founder of the Corpus Christianorum, Dom Dekkers, is no longer with us. But I will write to them and see if they will agree not to sue me if I use their version of the original text for these extracts.
If not, or if they want more than a nominal sum, I will print Mai’s text with an apparatus of the differences and a note as to why. But … who knows? I have had very good experiences with publishers so far.
