Diodati, Dominico an Italian scholar and archaeologist, was born at Naples 1736, and devoted himself especially to ecclesiastical studies. He is mentioned here on account of his De Christo Graece loquente, exercitatio, qua ostenditur Graecam sive Hellenisticam linguam cum Judaeis omnibus, tum ipse adeo Christo Domino, et apostolis nativam ac vernaculam fuisse (Neapoli. 1767; edited, with a preface, by Dobbin, Lond. 1843, sm. 8vo). The work seeks to prove that Christ and the apostles spoke only in Greek, and made use only of the Greek version of the Scriptures. See Am. Biblical Repository, 1:314.
