Priscian

A woman-grammarian, who corrects her husband for speaking false Latin, which is called breaking Priscian's head.

May Priscian himself be my enemy if what I am now going to say be not exactly true.

Priscian was a leading text-book on the subject, and it was supported by a short manual compiled from Donatus.

He devoted special attention to the early Latin writers, and is highly spoken of by Priscian.

Priscian the grammarian speaks of him as having attained the summit of honesty and of all sciences.
