While researching the significance of the various ways in which Latin speakers interpreted the phenomenon of grammatical gender, I spent a substantial amount of time examining ancient Roman scholars, in particular the Latin grammarians.1 Even a cursory reading of the accounts that these scholars have compiled about the masculine, feminine, and neuter soon reveals how they credit different poets with varying degrees of authority in the use and treatment of grammatical gender, even when that treatment may seem inconsequential to modern eyes. As one might expect, the grammarians regularly consider Vergil’s linguistic finesse indisputable, whereas they deem other poets, Lucan for example, to possess ‘lesser authority’ (minor … auctoritas).2 Evaluative remarks such as these prompted me to wonder what characteristics were thought to constitute the ‘poetic authority’ that informed scholars from antiquity in the evaluation and ranking of poets and whether these criteria affected the ways in which poetry was read and evaluated by ancient readers other than grammarians and other scholars.
