Apart from the fascinating hall and library, the buildings of Corpus are less distinguished than her history. The curious sundial, surmounted by a pelican vulning herself in piety, which stands in the centre of the front quadrangle, was erected by a fellow in 1581. As at All Souls' and elsewhere, the name of the college is indicated by sculpture over the gateway--a group of angels bearing a pyx, the receptacle of the sacramental host, the body of Christ (Corpus Christi). The pastoral staff, a chalice and paten, which belonged to the founder, are still preserved. They rank among the finest examples of the work of English mediæval silversmiths. The connection between Magdalen and C.C.C. was always close. Foxe, indeed, is said to have been at Magdalen, and to have [Illustration: First Quadrangle Corpus Christi College.] left Oxford on account of a pestilence. It is at any rate noteworthy that he makes special provision against plagues in his statutes. The severity and frequency of plagues of one sort or another were a serious obstacle to the prosperity of the University, and therefore of the city, throughout this century. The causes are not far to seek. For centuries filth and garbage had been allowed to accumulate in the ill-made, unswept streets. And though the King might write to the burghers and command them to remove the nuisances of this sort from before their doors, the efforts to deal with them were only spasmodic. Brewers and bakers, again, were forbidden by the King's edict (1293) to make use of the foul waters of Trill Mill Stream for the making of their bread and ale. But police was inefficient, and the health of the scholars frequently suffered from a renewal of this insanitary practice. Regrators, who burned before their doors stinking fat and suet, were also forbidden by Edward III. to pursue their habits, and the citizens were enjoined to repair the pavements in front of their houses. But in spite of regulations and restrictions butchers persisted in slaughtering their beasts in their homes and fouling the Trill Mill Stream with offal. Inundations from the Cherwell and the Thames, not yet regulated and confined by the Conservancy Board, occasionally swamped even the cloisters of Magdalen and left behind a legacy of mud, damp and malaria.
