De recta Diphthongorum pronunciatione Canones. Giovanni Battista. S J RICCIOLI.
THE 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 and the sole witness. Grammarian Pietro Marverti (b. 1620) and physician Pietro Tesei fought to a draw over the pronunciation of the Latin diphthongs appearing in aut, haud, ceu and seu. Marverti wrote to Riccioli: the Jesuit rhetorician and astronomer sided with him. Here we have Riccioli’s verdict and each sides’ arguments. I have not located a copy outside Europe. In good condition, stamp and 1890 release stamp of the Biblioteca Comunitativa Magnani (Bologna).
