This ritual of Dionysus, being made into a drama and falling into the hands of a remarkable set of creative artists, developed into what we know as Greek tragedy. The creative passion of the artist gradually conquered the emotion of the mere worshipper.
Exactly the same development took place in mediæval drama, or rather it was taking place when new secular influences broke in and destroyed it. The liturgical plays first enacted the main story of the New Testament; then they emphasized particular parts—there is a beautiful play, for instance, on the Massacre of the Innocents; then they developed imaginatively scenes that are implied but not mentioned in the Gospel, such as the experiences of the Magdalen when she lived "in joy," her dealings with cosmetic-sellers and the like; then, ranging right outside the Gospel histories, they dealt with the lives of St. Nicholas, St. Antony or any person who provided a good legend and had some claim to an atmosphere of sanctity.
