The Corinthian Speech (Corinthiaca) in the corpus of Dio Chrysostom (Or. 31) isattributed to Favorinus (c.80–160) based on internal criteria of content and style. Thisarticle argues that a reference to an author of a Corinthian speech found in a collectionof sayings in codex Vaticanus Graecus 1144 is a unique external reference to Favorinus asauthor of this speech.
