Caesar non supra grammaticos.

Definition

The Emperor is not above the grammarians.

Context / History

Its origin goes back to 1414, when the Holy Roman Emperor Sigismund of Luxembourg made a grammar mistake during his speech to the Council of Constance. After the error was pointed out to him, Sigismund angrily decided to simply change the grammar rule to his liking. At his point, a member of the Council apparently stood and said “Caesar non supra grammaticos”.
