The author of the treatise On Barbarism and Solecism is anonymous. This grammatical work dates from the Late Antique period, spanning approximately the second to sixth centuries CE, when such technical handbooks were central to the Greek educational system known as paideia. The author would have been a grammarian working within the established educational framework to teach the norms of classical Attic Greek.

The primary work is the treatise On Barbarism and Solecism, which systematically addresses linguistic errors. While the available metadata notes a works count of two, no other specific titles by this author are identified in the sources.

Treatises on barbarism, which denoted a word-level error, and solecism, a syntactic error, were foundational to the grammatical curriculum. They served a prescriptive function, policing what was considered correct Greek against the evolving common Koine dialect. This analytical framework, originating with the Stoic philosophers and later systematized by Alexandrian grammarians, became standard doctrine. The work is significant for understanding the linguistic ideologies and educational practices of the Greek-speaking world under Roman rule.
