The crypt of St. John’s Chapel (which, with the dungeons, is shown only to those who have obtained an order and are accompanied by a special warder), a very dark place before the comparatively modern windows were put in, was used as a prison cell, and here were confined those captured in the Wyatt rebellion. Prisoners’ inscriptions may still be seen on the wall on either side of the smaller dungeon, erroneously termed “Raleigh’s Cell.” This grim chamber, hollowed out of the wall of the crypt, would, when the door was shut and all light of day excluded, have been the most unwelcome hole for any human being to linger in. To assert that Raleigh sat and wrote here, by rushlight, is drawing too heavily on our credulity. Even “that beast Waad” would not have put his famous prisoner into such a place of darkness. The crypt has a remarkable barrel-shaped roof, the stones of which are most cunningly set together. The walls are of amazing thickness, as may be seen by the depth of the window recesses. Some few years ago a quantity of stained glass was found in this crypt; some of it of sixteenth-century date, the remainder modern and of little value. Fragments of this glass have been put together with care and skill and placed in the small windows of the Chapel of St. John, above.
