At first these words were sung responsively by the choir, but before the end of the tenth century they were put into the mouths of monks or clergy representing the Maries and the angel. By this time the dialogue had been removed to the first services of Easter morning, and had been connected with the ceremonies of the Easter sepulcher. In many churches it was then customary on Good Friday to carry a crucifix to a representation of a sepulcher which had previously been prepared somewhere in the church, whence the crucifix was secretly removed before Easter morning. Then, at the first Easter service, the empty sepulcher was solemnly visited, and this dialogue was sung.[1] The participants wore ecclesiastical vestments, and the acting was of the simplest character, but the amount of dialogue increased as time went on, and new bits of action were added; so that before the end of the twelfth century some churches presented what may fairly be called a short one-act play. Meanwhile, around the services of Good Friday and the Christmas season, other dramatic ceremonies and short dialogues had been growing up, which gave rise to tiny plays dealing with the birth of Christ, the visits of the shepherds and the Wise Men, and the Old Testament prophecies of {23} Christ's coming. Although the elaboration of individual plays continued, the evolution of the drama as part of the Church's liturgy was practically complete by the middle of the thirteenth century. +The Earlier Miracle Plays+.--The next hundred years brought a number of important changes: the gradual substitution of English for Latin, the removal from the church to the churchyard or market-place, and the welding together of the single plays into great groups or cycles. The removal from the church was made possible by the growth of the plays in length and dramatic interest, which rendered them independent of the rest of the service; and it was made inevitable by the enormous popularity of the plays and by the more elaborate staging which the developed plays required. The formation of more or less unified cycles was the result of a natural tendency to supply the missing links between the plays already in existence, and to write new plays describing the events which led up to those already treated. Just as Wagner in our day after writing his drama on _The Death of Siegfried_ felt himself compelled to write other plays dealing with his hero's birth and the events which led to this birth, so the unknown authors of the great English cycles were led to write play after play until they had covered the significant events of Biblical history from the creation of the world to the Last Judgment. This joining together of isolated plays necessitated taking them away from the particular festivals with which they had originally been connected and presenting them all together on a single day, or, in the case of the longer cycles, on successive days. After 1264, {24} when the festival of
