De recta Diphthongorum pronunciatione Canones. Giovanni Battista. S J RICCIOLI.
THE CORREGGIO DIPHTHONG WAR OF 1667

De recta Diphthongorum pronunciatione Canones.

Modena, A. Cassiani 1667.

Small 8vo. Etched allegorical title, 442, [22]p.

Contemporary boards, later marbled paper spine covering (chipped) and labels.

Shockingly, the only edition: the sole witness to the Diphthong War. Correggio grammarian Pietro Marverti (b. 1620) entered the lists against local physician Pietro Maria Tesei over the pronunciation of the Latin diphthongs aut, haud, ceu and seu. As neither could claim victory after protracted pen-to-pen combat, Marverti wrote to Riccioli, the Jesuit rhetorician and astronomer, who sided with the appellant. Here Marverti touts his triumph and prints Riccioli’s thirty-page verdict in full followed by each sides’ many sallies. The Modena Jesuits took offense at the appearance in print of one of their own without the Society’s permission and went after Marverti. I have not located a copy outside Europe. In good condition, Biblioteca Communitativa Magnani (Bologna) stamp and release stamp (dated 1890) on the title verso.
