The tomb of Galeotto Bernardini, patrician from Lucca and protonotary apostolic, on the first pillar of the south aisle belongs to the group of elaborate Baroque funeral monuments. Bernardini died in 1591 at the age of 30. The epitaph mentions that he was a trusted confidant of Cardinal Marco Sittico Altemps, and he served with distinction under Popes Urban VII and Gregory XIV. The sepulchre was erected by the late protonotary's brother, Lorenzo Bernardini.
