Life of Baldassare Castiglione

Between Mantua and Urbino

He was born at Casatico, near Mantua, on 6 December 1478. The son of Cristoforo Castiglione and Luigia, also called Aloisa, Gonzaga, he was educated in the humanist environment of Milan. From 1504 he served the dukes of Urbino, whose courtly life provided the literary setting for his work.

The Courtier and diplomacy

The Book of the Courtier, published in Venice in 1528, presents conversations about the education and conduct of the courtier and the court lady. His literary activity accompanied diplomatic missions in Rome and Spain. Appointed nuncio in 1524, he had to confront the tensions between Clement VII and Charles V and the accusations that followed the Sack of Rome in 1527.
