pastoral staff; perhaps it represents the shrine with its attendants. From the style of art, this design may be of the early part of the thirteenth century. But though this ampul is clearly designated by the monkish writers, whom we have quoted, as the special sign of the Canterbury pilgrimage, there was another sign which seems to have been peculiar to it, and that is a bell. Whether these bells were hand-bells, which the pilgrims carried in their hands, and rang from time to time, or whether they were little bells, like hawks' bells, fastened to their dress--as such bells sometimes were to a canon's cope--does not certainly appear. W. Thorpe, in the passage hereafter quoted at length from Fox, speaks of "the noise of their singing and the sound of their piping, and the jangling of their Canterbury bells," as a body of pilgrims passed through a town. One of the prettiest of our wild-flowers, the _Campanula rotundifolia_, which has clusters of blue, bell-like flowers, has obtained the common name of Canterbury Bells.[197] There were other religious trinkets also sold and used by pilgrims as mementoes of their visit to the famous shrine. The most common of them seems to have been the head of St. Thomas,[198] cast in various ornamental devices, in silver or pewter; sometimes it was adapted to hang to a rosary,[199] more usually, in the examples which remain to us, it was made into a brooch to be fastened upon the cap or hood, or dress. In Mr. C. R. Smith's "Collectanea Antiqua," vol. i. pl. 31, 32, 33, and vol. ii. pl. 16, 17, 18, there are representations of no less than fifty-one English and foreign pilgrims' signs, of which a considerable proportion are heads of St. Thomas. The whole collection is very curious and interesting.[200] [Illustration: _The Canterbury Ampulla._]
