"St. Peter in Prison (The Apostle Peter Kneeling)" by Rembrandt van Rijn

Rembrandt’s painting shows the apostle Peter in his prison cell in Jerusalem following his arrest. A shaft of soft, golden light falls on him from an unseen source, leaving large parts of the painting in total obscurity. The saint’s attribute is clearly visible, however: two large metal keys signifying the keys to the kingdom of Heaven bestowed on him by Jesus, which in this situation suggest the irony of his jailed state.
