(1619–76). Florentine patrician and man of letters, professor of classics at the Florentine studio [see Universities, 1], and later librarian to Prince Leopoldo. A pupil of Galileo, and a member of several academies, Dati's interests included natural philosophy and the history of art, but he is best known for his concern with language, as secretary of the Accademia della Crusca and the author of the Discorso sull'obligo di ben parlare la propria lingua (1657). [See also Questione Della Lingua.]
