The Use of Greek in Diomedes’ Ars Grammatica

Written around the last years of the fourth century AD, the Ars Grammatica of Diomedes was intended to Greek-speaking people who wanted to learn Latin. Therefore, like Dositheus and Charisius, this text has to be placed in a bilingual context, more specifically in the region of Constantinople, the late capital of the Eastern Roman Empire, where the grammar might have been published. I would like to explore the traces of bilingualism we can detect in this text, especially the Greek words, with a particular attention paid to the intrasentential code-switchings, in order to illustrate the dynamics of the coexistence of Greek and Latin in an ancient grammatical work
