At the summit of the ridge a small roadside cottage, known as "Chapel Bush," represents the once famous shrine of "Our Lady of White Hill"; in mediaeval days a noted centre of local devotion, which drew pilgrims in large numbers from a wide area, so that their accommodation, as we read, was no small profit (and, often, difficulty) to the neighbouring villages. No ruins, even, of this ancient chapel remain; but, in 1885, there was discovered on its site a leaden _bulla_ of Pope Martin the Fifth, the first Pope to be generally acknowledged after the Great Schism; when for forty years two (or three) claimants to the Holy See were reigning simultaneously, supported some by one part of Christendom, some by another. He reigned 1417 to 1431, and was the consecrator of Milan Cathedral. It was he who, at the "Assize of Barnwell" (1430), pronounced that all spiritual jurisdiction over the students of Cambridge was exclusively vested in the University authorities. His _bulla_ bears the heads of SS. Peter and Paul, with the traditional features, which Lanciani has now established as historical; St. Peter having a broad face with curly hair and beard, while St. Paul is thin-faced and straight-haired. On the southern side of the hill lies Barrington, perhaps the loveliest of all Cambridgeshire villages. It consists of two long lines of scattered cottages, straggling along either side of a Village Green nearly a mile in length. The Green is traversed from end to end by the "Church Path," a pebbled causeway of immemorial antiquity. The church, to which this leads, stands at the north-eastern extremity of the Green, and is a noble structure of the twelfth century, with later developments. The south doorway and door are thirteenth century, and are wonders of graceful work; while the fourteenth century seats are of special interest as having been constructed with book-boards, showing that reading was not the rare accomplishment in those days that it is commonly supposed to have been.[174] There is also an iron-bound chest dating from the tenth century, a splendid specimen of the smiths-work for which England was then so famous. The font, too, is equally old, showing on its margin the depressions (now filled in), often provided in fonts of the period when baptism by immersion was the rule, as outlets for accidental overflow. [Footnote 174: The Chantry Priests, of whom there were two in Barrington, often acted as village schoolmasters, the Chantries themselves serving as classrooms.] [Illustration: _Farmhouse at Haslingfield._]
