There is a Tertullian quote in one of the editions of Gibbon (see the asterisked note here for the original).
Nam proximè ad lenonem damnando Christianam, potius quam ad leonem, confessi estis labem pudicitiae apud nos atrociorem omni poenâ et omni morte reputari, Apol. capult.
I searched and found the Tertullian quote, thus discovering that the "Apol. capult." isn't part of the quote. The "Apol." is for Apologeticus, the source of the quote.
What I can't find is the "capult." I've done quite a bit of searching, and I can't find that word in any Latin dictionary, nor can I find it as an abbreviation (in case that period is doing double-duty).
Is "capult" a word or an abbreviation, if the latter what is it an abbreviation for, and what does it mean in this context?
