Giovanni della Casa

Giovanni della Casa (28 July 1503 – 14 November 1556), was a Florentine poet, writer on etiquette and society, diplomat, and inquisitor. He is celebrated for his famous treatise on polite behavior, Il Galateo overo de’ costumi (1558). From the time of its publication, this courtesy book has enjoyed enormous success and influence. In the eighteenth century, influential critic Giuseppe Baretti wrote in The Italian Library (1757), "The little treatise is looked upon by many Italians as the most elegant thing, as to stile, that we have in our language."
