The paper, arranged in three parts, discusses two autograph works by Domenico Beccafumi, one of which previously unpublished, and a derivation from the Magnani Rocca painting. The 'Virgin and Child with Saints Catherine of Alexandria and Lawrence', following its discovery, is reproposed here, allowing us to admire its extraordinary colours. Published for the first time is a precious oil on paper with 'Saint Catherine of Siena receiving the Stigmata' of the painter's final years, and lastly a 'Holy Family with the Young Saint John and Saint Catherine of Siena', not an autograph work but almost certainly coming from the painter's workshop. The latter has the same composition as the 'Virgin and Child with the Young Saint John the Baptist, Saints Elizabeth and Catherine of Siena' of the Fondazione Magnani Rocca, except for the replacement of John's mother with Saint Joseph.
