The founders of the Accademia della Crusca are traditionally identified as Giovanni Battista Deti ('Sollo'), Antonio Francesco Grazzini ('Lasca'), Bernardo Canigiani ('Gramolato'), Bernardo Zanchini ('Macerato'), Bastiano de' Rossi ('Inferigno'); they were joined in October 1582 by Lionardo Salviati[6] ('Infarinato') (1540–1589). Under his leadership, at the beginning of 1583, the Accademia took on a new form, directing itself to demonstrate and to conserve the beauty of the Florentine vulgar tongue, modelled upon the authors of the Trecento.[7]
