The masons who worked here liked their joke; and one of them made a boss of foliage, graceful enough when seen from above,--but stoop down to look at it from below, and behold a grinning imp. This stonework was chiselled _in situ_, the rough blocks were placed where they were to stay, and there they were cut into the shape required, several being even yet unfinished. Canopied niches abound here, but of the statuary that once filled them one figure alone has escaped destruction, and still indicates how beautiful its companions must have been. To Bishop Alcock Jesus College, Cambridge, owes its existence, and Peterhouse many benefactions; and here is his tomb. In 1900 Bishop Alwyne Compton filled the window of this chapel with stained glass, depicting four of his most noted predecessors. Leaving this chantry behind we see on our right, under his own Early English bays, the monument to our old friend, Hugh de Northwold, who lies buried not in this spot but in the middle of his presbytery. Before he became Bishop of Ely he had been Abbot of Bury St. Edmund's, for which place he ever retained a warm affection. His feet touch a block of marble, on which is sculptured the martyrdom of St. Edmund, whom we see tied to a tree and shot to death by Danish arrows, while his beheading is also represented. Here, too, is a wolf guarding the Saint's head, according to the legend. The story ran that, after the Saint's martyrdom and decapitation, his surviving subjects, to whom his "universal graciousness which yet suffered no unbecoming familiarity" had deeply endeared him, sought, so soon as the Danes had marched away, to take up his remains for fitting burial. The body they soon found, but the head had been cast into a thicket, and was not discovered till the searchers heard a voice crying, "Here! Here! Here!" which guided them to the spot where it lay. A huge wolf was standing, as it were, on guard over the sacred relic, but did not offer to attack the finders, who, on their part, suffered it to remain unhurt. The faithful beast followed them like a dog till it saw the head laid together with the body, and then quietly departed into the forest, no man doing aught against it. Close at hand, leaning against the northern wall of the aisle, is a detached fragment of stonework, once the arm of Northwold's abbatial chair which he brought with him from Bury St. Edmund's. This, too, is made in the form of a beast of prey (somewhat distantly resembling a wolf), holding between its paws a human head. The Abbey of Bury St. Edmund's, it may be mentioned, was, in some sort, a daughter House of Ely. When King Edgar, "the Peacemaker," founded that monastery in honour of the Royal Martyr he populated it, in the first instance, by drafting forty monks from Etheldreda's earlier royal foundation.
