Heads of Judas and Peter 

This drawing, "Heads of Judas and Peter," is a study by Leonardo da Vinci for the Last Supper. Da Vinci's detailed and realistic approach to human emotion can be seen in the expressive faces of the two apostles. The drawing is executed in red chalk and black chalk, a common medium for preliminary studies in Renaissance Italy. The study, now held in the Ackland Art Museum in Chapel Hill, NC, is a testament to da Vinci’s meticulous process and his deep interest in human psychology.
