The monument of a Prussian painter, Franz Ludwig Catel was erected by the pillar between the Della Rovere and Cybo Chapels. Catel was a successful landscape and genre painter who spent most of his career in Rome. He lived nearby in Piazza di Spagna where his home became a favourite meeting place for young artists. He died in 1856 at the age of 78 years and left his estate to a foundation which he had set up to help young German and Italian artists in the city. His monument was designed by a fellow German sculptor, Julius Troschel.
