Much important work of various kinds has been done in the Jerusalem Chamber. The Assembly of Divines held its meetings here in 1643, during the time of the Commonwealth, and drew up the Longer and Shorter Catechism, and the Confession of Faith, known as the “Westminster Confession.” Here, too, the Revisors of the Old and New Testaments used to meet for their great work, which began in 1870. [Illustration: [_D. Weller_. THE JERUSALEM CHAMBER. ] The Jerusalem Chamber is now used as the Chapter-House, because the actual Chapter-House still belongs to the Government, and not to the Abbey. The College Hall, which was built by Abbot Litlington to be his refectory or dining-hall, is now used as the dining-hall for the Westminster scholars. It is a beautiful room, with long windows in the Early Perpendicular style, and a minstrels’ gallery at one end. The fireplace, or stove, is in the middle of the room, and gives it a very old-world look. The long tables in the hall are said to be made of chestnut wood from the wrecked ships of the Spanish Armada, and to have been given to the school by Queen Elizabeth. The College Hall forms one side of the old courtyard of the “Abbot’s place” (or palace) as it was called, part of which house is now the Deanery. Litlington’s successor, Abbot Colchester, is said to have joined in a conspiracy against Henry IV. This story was evidently accepted by Shakspeare, for in his play, _King Richard II_, he writes— “The grand Conspirator, Abbot of Westminster, With clog of conscience and sour melancholy, Hath yielded up his body to the grave.” There is, however, no good foundation for the story of Abbot Colchester’s conspiracy, and he lived on quietly until 1420. Two of the Abbots of Henry VII’S reign, Abbot Esteney and Abbot Islip, did a good deal of building in the church and precincts. The great West Window was set up in Abbot Esteney’s time, and the tracery shows how entirely different the Perpendicular style of architecture is from the Early English, in which the rest of the Abbey is built. The glass of the West Window was put in much later, during the reign of George II. In Abbot Islip’s time Henry VII’s Chapel was built, the Abbot himself laying the foundation-stone. The western towers were carried up as far as the roof, and some rooms were added to the Abbot’s house. One of these is the charming panelled room known as the Jericho Parlour.
