Which work was NOT published in the venacular during the Middle Ages?

One significant work that was not published in the vernacular during the Middle Ages is "The Divine Comedy" by Dante Alighieri, which was written in Italian but was initially influenced by Latin texts and styles. While it is now celebrated for its use of the vernacular, the period's predominant literary output often favored Latin, particularly for scholarly and religious works. Thus, many important texts of the time remained accessible primarily to those fluent in Latin, rather than the vernacular languages spoken by the general populace.
