The Penitent Saint Peter 

This painting by the Italian Baroque artist Guido Reni depicts Saint Peter, one of Jesus' disciples. The artwork focuses on Saint Peter's emotional state as he is shown with his head bowed and his hands clasped in prayer. The soft light and subtle use of color heighten the sense of quiet contemplation that permeates the composition, making this piece a fine example of Reni's skill in portraying emotional depth in his subjects. This is a great example of a Baroque painting that focuses on emotion and introspection.
