Baldesar Castiglione was born in 1478, a member of an ancient Italian aristocratic family. He received a thorough humanistic education, acquiring a refined appreciation of art. He was essentially a courtier, and his literary activities were spare-time occupations. In 1504, after an unhappy period in Mantuan employ, he entered the service of Guidobaldo of Montefeltro, Duke of Urbino. The ensuing years were the most satisfying of his life. He enjoyed the confidence of the Duke, who frequently entrusted him with important missions, and in his leisure moments he participated in the literary and intellectual activities of the court, then one of the most brilliant in Italy.After Guidobaldo's death in 1508, he remained in the service of the new Duke, Francesco Maria della Rovere, becoming, in 1513, resident ambassador in Rome. In 1515 the expulsion of Francesco Maria from Urbino deprived him of a job, and in the years 1516 to 1519 he lived quietly on his estates near Mantua. His major work is The Book of the Courtier. He also wrote a small number of excellent poems both in Latin and Italian. In 1519 he returned to Rome, as Mantuan ambassador, and after further activities on behalf of his Mantuan masters entered Papal service in 1524. From that date until his death in 1592 he was Papal Nuncio in Spain.
