has, of course, strictly no right to that name. Obviously it cannot be the church of "wondrous dimensions" built by Pain Peverel. The chapel, although in all likelihood it did stand within the Priory precincts, was most probably built for the use of the inhabitants of the parish by the canons, in order that they themselves might be left undisturbed in the exclusive use of the Conventual Church. It is a building of the early English style, with long, narrow lancet windows, evidently belonging to the early part of the thirteenth century. [Illustration: Chapel Barnwell Priory] The material remains of the Priory are therefore very meagre, but a most interesting insight into the domestic economy of a monastic house is afforded by the "_Consuetudinarium_; or, Book of Observances of the Austin Canons," which forms the Eighth Book of the Barnwell Cartulary, to which we have already alluded. A comparison of the domestic customs of a monastic house in the thirteenth century, as shown in this book, and of the functions of its various officers, with many of the corresponding customs and functions in the government of a Cambridge college, not only in mediæval but in modern times, throws much light on the origin of some of the most characteristic features of college life to-day.[12] Let us retrace our steps, however, along the Barnwell Road from the suburban monastery to the ancient town. There are still some features, belonging to the Norman structure of Cambridge, which demand our notice before we pass on. At a point where the High Street, now Trinity Street, branches off from Bridge Street stands the church of the Holy Sepulchre, one of the four round churches of England.[13] [Illustration: The Round Church]
