At first such plays were given in the church, and were deeply religious in spirit. They made a profound impression in England especially, where people flocked in such numbers to see them that presently they overflowed to the churchyard, and from there to the city squares or the town common. Once outside the church, they were taken up by the guilds or trades-unions, in whose hands they lost much of their religious character. Actors were trained for the stage rather than for the church, and to please the crowds elements of comedy and buffoonery were introduced, [Footnote: In the "Shepherd's Play" or "Play of the Nativity," for example, the adoration of the Magi is interrupted by Mak, who steals a sheep and carries it to his wife. She hides the carcass in a cradle, and sings a lullaby to it while the indignant shepherds are searching the house.] until the sacred drama degenerated into a farce. Here and there, however, a true Miracle survived and kept its character unspotted even to our own day, as in the famous Passion Play at Oberammergau. [Sidenote: CYCLES OF PLAYS] When and how these plays came to England is unknown. By the year 1300 they were extremely popular, and continued so until they were replaced by the Elizabethan drama. Most of the important towns of England had each its own cycle of plays [Footnote: At present only four good cycles of Miracles are known to exist; namely, the Chester, York, Townley (or Wakefield) and Coventry plays. The number of plays varies, from twenty-five in the Chester to forty-eight in the York cycle.] which were given once a year, the performance lasting from three to eight days in a prolonged festival. Every guild responsible for a play had its own stage, which was set on wheels and drawn about the town to appointed open places, where a crowd was waiting for it. When it passed on, to repeat the play to a different audience, another stage took its place. The play of "Creation" would be succeeded by the "Temptation of Adam and Eve," and so on until the whole cycle of Miracles from "Creation" to "Doomsday" had been performed. It was the play not the audience that moved, and in this trundling about of the stage van we are reminded of Thespis, the alleged founder of Greek tragedy, who went about with his cart and his play from one festival to another. [Sidenote: MORALITIES] Two other dramatic types, the Morality and the Interlude, probably grew out of the religious drama. In one of the old Miracles we find two characters named Truth and Righteousness, who are severe in their denunciation of Adam, while Mercy and Peace plead for his life. Other virtues appear in other Miracles, then Death and the Seven Deadly Sins, until we have a play in which all the characters are personified virtues or vices. Such a play was called a Morality, and it aimed to teach right conduct, as the Miracles had at first aimed to teach right doctrine. [Sidenote: INTERLUDES]
