Paintings conservator Cristina Morilla takes a close look at Peter Paul Rubens's oil sketch "Hercules strangling the Nemean Lion,” commissioned by King Philip IV of Spain. Although the larger painting of “Hercules strangling the Nemean Lion” that once hung on the walls of the Royal Palace of Madrid is now lost, Cristina discusses how different analytical investigations of the sketch, such as infrared photography, Ultraviolet photography, and other scientific methods, shed light on Rubens’s technique and reveal the secrets of the master.
