church, may be opened out and restored to its original position as part of the main crypt. According to Gervase, the whole of the crypt was dedicated to the Virgin Mary. Here stood the Chapel of Our Lady Undercroft, surrounded by Perpendicular stone-work screens, from which the altar-screen in the choir above was imitated. The shrine of the Virgin was exceedingly rich and was only shown to privileged worshippers: traces of decoration may still be seen in the vault above. It was at the back of this shrine that Becket was laid between the time of his murder and his translation to the resting-place in the Trinity Chapel. In the main crypt we may notice the monument of Isabel, Countess of Athol, who died in 1292; she was heiress of Chilham Castle, near Canterbury, and grand-daughter of King John. She was twice married, her second husband being Alexander, brother of John Baliol, King of Scotland. The monument of Lady Mohun of Dunster is in the south screen of the Chapel of Our Lady. She was ancestress of the present Earl of Derby, and founded a perpetual chantry. Lastly, here is the tomb of Cardinal Archbishop Morton, the friend of Sir Thomas More, and the faithful servant of the House of Lancaster; it was he who brought about the union of the Red and White Roses by arranging the marriage of Henry of Richmond with Elizabeth of York. As Henry VII.'s Chancellor he made great exactions under the euphonious title of "Benevolences," and propounded the famous dilemma known as "Morton's Fork," by which he argued that those who lived lavishly must obviously have something to spare for the king's service, while those who fared soberly must be grown rich on their savings, and so were equally fair game to the royal plunderer. He lies in the south-west corner of the crypt, and his monument, which has suffered considerably at the hands of the Puritans, bears the Tudor portcullis and the archbishop's rebus, a hawk or _mort_ standing on a tun.
