The lives of Jesus and Buddha, the founders of new religions, their followers, and in the case of Buddha also the former lives, were to provide new subject-matter for narrative art, as did elements of older religions such as the Labours of Hercules. Trajan's Column is an exceptional example of Imperial Roman narrative art. In Christian art the Life of Christ in art and Life of the Virgin supplied the most common subjects, based around the incidents celebrated in the major feasts of the church calendar, but the lives of saints gave many others.
