Uría Javier. Septimus casus: the history of a misunderstanding from Varro to the late Latin grammarians

Journal of Latin Linguistics. — 2017. — Vol. 16. Issue 2. — p. 239-266.This paper reviews approaches to what is known as the septimus casus from Varro and Quintilian to the late grammarians. It emphasizes the different points of view adopted to describe the seventh case in the history of Latin grammar, and suggests that some descriptions have arisen from simple misinterpretations of earlier sources. The paper confirms that Varro may have had a concept of a seventh case. Interestingly, an unnoticed connection has been detected between the earliest approaches and those in Servius’s commentaries on Vergil, where the opinion differs greatly from those in the artes grammaticae.
