Saint Peter as Pope (1610–1612) by Peter Paul Rubens - Public Domain Catholic Painting

Saint Peter (died between AD 64 and 68), also known as Simon Peter, Simeon, Simon, or Peter the Apostle, was one of the Twelve Apostles of Jesus Christ, and one of the first leaders of the early Church.

According to Christian tradition, Peter was crucified in Rome under Emperor Nero. He is traditionally counted as the first bishop of Rome‍—‌or pope‍—‌and also by Eastern Christian tradition as the first patriarch of Antioch. The ancient Christian churches all venerate Peter as a major saint and as the founder of the Church of Antioch and the Diocese of Rome, but differ in their attitudes regarding the authority of his successors. According to Catholic teaching, Jesus promised Peter—and all his successors—a special position in the Church. Source

Sir Peter Paul Rubens (28 June 1577 – 30 May 1640) was a Flemish artist and diplomat from the Duchy of Brabant in the Southern Netherlands (modern-day Belgium). He is considered the most influential artist of the Flemish Baroque tradition. Rubens's highly charged compositions reference erudite aspects of classical and Christian history. His unique and immensely popular Baroque style emphasized movement, color, and sensuality, which followed the immediate, dramatic artistic style promoted in the Counter-Reformation. Rubens was a painter producing altarpieces, portraits, landscapes, and history paintings of mythological and allegorical subjects. He was also a prolific designer of cartoons for the Flemish tapestry workshops and of frontispieces for the publishers in Antwerp. Source
