He exhibited frequently, earning honorable mention at the National Exhibition of Fine Arts in 1864 and 1867.^[1] Some of his best-known works include posthumous portraits of Miguel de Cervantes and Pedro Rodríguez, Count of Campomanes, as well as episodes from the life of Saint Teresa.

He created an "Allegory of Philosophy" for the Ateneo de Madrid and worked with his brother, creating figures of Saints Mark and Matthew for the Iglesia del Buen Suceso.^[1]
