Roman lyric poet, satirist, and translator, remembered chiefly for his translation of Virgil's Aeneid and for the elegant style of his letters.

Secretary first to Msgr. Giovanni Gaddi in Florence and in Rome, then to Cardinal Pier Luigi Farnese, Caro received benefices that freed him to write. His poetry, collected as Rime in 1569, and his satires are unimportant.

Caro's most outstanding works are his free and graceful Lettere familiare (pub. 1572–74; “Familiar Letters”) and a smooth translation of Virgil's Aeneid (1581). He also wrote one of the most original comedies of his time, Straccioni (completed 1544), and a version of Longus' Daphnis and Chloe called Amori pastorali di Dafni e Cloe (“The Pastoral Loves of Daphnis and Chloe”).
