This work examines for the first time a collection of more than 450 carmina ascribed to Perfetto Corazzini (1480-1540 ca.). He was a minor penitencer in S. Maria Maggiore, a preceptor for noble families and a skilled versifier. He lived in Rome under the protection of Paul III. The collection is divided into two anthologies, containing poetic compositions by Corazzini and by other authors, mostly unpublished. It is preserved in a single apograph copy in Berkeley, Bancroft Library, ms. UCB 77.
