Returning from the crucifixion with Demetrius, Marcellus uses the robe in an attempt to shield himself from a rain squall, but feels a sudden crushing guilt for crucifying Jesus and tears the robe off. In a fit of rage, Demetrius curses Marcellus and the Roman Empire and runs away, taking the robe with him. Marcellus now behaves like a madman haunted by nightmares of the crucifixion. He reports to Emperor Tiberius at Capri, who gives him an imperial commission to find and destroy the robe, while gathering a list of names of Jesus' followers. At Diana's request, Tiberius leaves her free to marry Marcellus, though Tiberius believes Marcellus is mad.
