Gianfrancesco Penni, Italian Renaissance artist, or his brothers Luca and Bartolomeo
Following Raphael's death in 1520, his assistants Gianfrancesco Penni, Giulio Romano and Raffaellino del Colle finished the project with the frescoes in the Sala di Costantino.
He had an Italian colleague Bartolommeo Penni, brother of the much more distinguished Luca and Gianfrancesco, Raphael's right hand man.
Though it is believed that Raphael did make the designs for the composition, the fresco was probably painted by Gianfrancesco Penni.
After the master's death in 1520, Gianfrancesco Penni, Giulio Romano and Raffaellino del Colle from Raphael's workshop worked together to finish the commission to decorate with frescoes the rooms that are now known as the Stanze di Raffaello, in the Apostolic Palace in the Vatican.
