This 15th-century painting by the Master of the Legend of Saint Ursula depicts the Crucifixion of Saint Peter, a key event in Christian history. In Northern Renaissance style, the artwork emphasizes realism, intricate detail, and spiritual devotion. According to tradition, Peter was crucified upside down at his request, feeling unworthy to die like Christ. His martyrdom is significant as he is considered the first Pope and a cornerstone of Christianity.

John 21:18-19, foretells his fate:
"When you are old, you will stretch out your hands, and someone else will dress you and lead you where you do not want to go."
