lest they might mar the youth’s style. His numerous private and official letters have preserved many valuable facts and furnish interesting illustration of contemporary manners and character. Humboldt praises him as the first Italian author to write attractive descriptions of natural scenery, and cites especially his dialogue on Mt. Ætna. [Illustration: GIACOMO SADOLETO 1477-1547 ] Head enlarged from a photograph, specially made by Alinari, of a part of the fresco, “Leo X's Entry into Florence,” in the Palazzo Vecchio at Florence, by Giorgio Vasari (1511-1574). See Milanesi’s edition of Vasari’s _Opere_, viii, 142. The chief facts of his life are given in note 242, at page 369 of this volume. Note 43 page 12. CESARE GONZAGA, (born about 1475; died 1512), was a native of Mantua, being descended from a younger branch of the ruling family of that city, and a cousin of Castiglione, with whom he maintained a close friendship. His father’s name was Giampietro, and he had a brother Luigi. Having received a courtly and martial education at Milan, and after spending some time with his relatives at Mantua, he entered the service of Duke Guidobaldo of Urbino. In 1504 he shared Castiglione’s lodgings after their return from a campaign against Cesare Borgia’s strongholds in Romagna, and in the carnival of 1506 they together recited Castiglione’s eclogue _Tirsi_, in the authorship of which he is by some credited with a part. A graceful canzonet, preserved in Atanagi’s _Rime Scelte_, attests his skill in versification. On Guidobaldo’s death in 1508, the two friends remained in the service of the new duke, Francesco Maria. In 1511 Cesare fought bravely against the French at Mirandola, and the next year took part in the reduction of Bologna, where he soon died of an acute fever. Little more is known of him, beyond the fact that he was a knight of St. John of Jerusalem, that Leo X sent him on a mission to Charles V of Spain, and that he was among the many friends of the famous Isabella d'Este (see note 397).
