 In the early 17th century, some literary masterpieces were created, such as Giambattista Marino's long mythological poem, "L'Adone".The Baroque period also produced the clear scientific prose of Galileo as well as Tommaso Campanella's "The City of the Sun", a description of a perfect society ruled by a philosopher-priest.At the end of the 17th century, the Arcadians began a movement to restore simplicity and classical restraint to poetry, as in Metastasio's heroic melodramas.
