This article examines a brief mention of the Egyptian gods Apis and Serapis in the Aduersus nationes by Arnobius of Sicca. This reference is situated within the context of several traditions dealing with the origin and connections of both of these mythical figures transmitted with some variations until Late Antiquity. It is proposed that the Peloponnesian Apis is identified with the Egyptian Serapis through a tradition already attested in Classical Greek authors, though without it being possible to determine which author is the specific reference for the Arnobian text.
