The various craft guilds took part in the Mysteries and Miracles, which were rudimentary dramas, founded on Bible history or on the stories of the lives of the saints. Each of the fifty-four crafts produced a separate pageant. The plays took place on Corpus Christi Day, which fell the Thursday after Trinity Sunday, and were enacted on movable stages which could be wheeled from place to place. The performances, which were carried on simultaneously in a dozen different stations in the city, enjoyed a great popularity, and this was one of the reasons for building the Guildhall, that a commodious theatre was needed for these productions. During the sixteenth century plays were performed in the Guildhall by itinerant companies of players, who attached themselves either to the sovereign or to some prominent nobleman. The stately hall is divided into nave and aisles by two rows of octagonal oak pillars which support timber arches carrying a low-pitched roof. The windows are filled with modern painted glass depicting events in the history of York. The room behind, with its panelling concealing staircases, is that in which two hundred thousand pounds were paid to the Scottish army for handing over Charles I to the English Parliament. The towers and spires of the churches add much to the charm of the city. Though the churches are small, they are full of interesting objects. The earliest work is the tower of St. Mary, Bishophill Junior, which exhibits all the features of pre-Conquest architecture. St. Mary’s, Castlegate, possesses an extremely interesting stone of the eleventh century, recording that, “This Minster was set up by Eferaud and Grim and Æse in the name of the Lord Jesus Christ and St. Mary and St. Martin and St. Cuthbert and All Saints and was consecrated in the year----” The old church of St. Lawrence, with the exception of the tower, has been taken down and a new church erected on an adjoining site. Sir John Vanbrugh, the dramatist and architect of Blenheim and Castle Howard, was married in the old church. The doorway to the nave has been preserved and rebuilt as the tower doorway. This beautiful example of Norman work forms the subject of one of the pictures. The tower is now the only relic of the eight churches which formerly stood within the area of the present parish. During the siege of York in the seventeenth century, this churchyard formed the base of the Parliamentarian attack on Walmgate Bar, three thousand men being engaged. As a consequence, the church was demolished, but subsequently rebuilt. The quaint parish stocks are within the churchyard gates.
