You need to specify which Claudio you are referring to, because there are a few famous Claudios, but since you ask what era, I presume that you mean Claudio Monteverdi. He was baptized on May 15, 1567 and died on November 29, 1643. Monteverdi would best be fit in the Baroque era, because of his music style and the time period he lived in. The Baroque era was from 1600 to 1750. Claudio was one of the composers who brought about the change from Renaissance style music to Baroque music.
