Born Dec. 6, 1478, in Casatico, near Mantua; died Feb. 2, 1529, in Toledo, Spain. Italian writer.
Castiglione’s best-known work is The Courtier (books 1–4, 1528), a treatise in dialogue form. In the spirit of late humanism, Castiglione enumerated the qualities of the ideal courtier, or, in a broader sense, of the well-brought-up, broadly educated man with a developed personality. This ideal was current throughout Europe in the 16th and early 17th centuries and was reflected in literature.
