The shape in the thirteenth and fourteenth century presented a stiff low triangle in front and behind, with a gap between them. It is well shown in a MS. of the close of the twelfth century, Harl. 2,800, f. 6, and, in a shape a little further developed, in the pictures in the Royal MS., 2 B. vii., already noticed. In the fifteenth century the mitre began to be made taller, and with curved sides, as seen in the beautiful woodcut of a bishop and his canons in choir given in our last chapter, p. 197. The latest example in the English Church is in the brass of Archbishop Harsnett, in Chigwell Church, in which also occur the latest examples of the alb, stole, dalmatic, and cope. The pastoral staff also varied in shape at different times. The earliest examples of it are in the representations of St. Mark and St. Luke,[296] in the "Gospels of MacDurnan," in the Lambeth Library, a work of the middle of the ninth century. St. Luke's staff is short, St. Mark's longer than himself; in both cases the staff terminates with a plain, slightly reflexed curve of about three-fourths of a circle. Some actual examples of the metal heads of these Celtic pastoral staves remain; one is engraved in the "Archæologia Scotica," vol. ii., another is in the British Museum; that of the abbots of Clonmacnoise, and that of the ancient bishops of Waterford, are in the possession of the Duke of Devonshire. They were all brought together in 1863 in the Loan Exhibition at South Kensington. One of the earliest English representations of the staff is in the picture of the consecration of a church, in a MS. of the ninth century, in the Rouen Library, engraved in the "Archæologia," vol xxv. p. 17, in the "Pictorial History of England," and by Dr. Rock, ii. p. 24. Here the staff is about the length of an ordinary walking-stick, and is terminated by a round knob. Odo, Bishop of Bayeux, is represented on his great seal with a short staff, with a tau-cross or crutch head. An actually existing staff of this shape, which belonged to Gerard, Bishop of Limoges, who died in 1022, is engraved in the "Annales Archæologique," vol. x. p. 176. The staves represented in illuminations of the twelfth and thirteenth centuries have usually a plain spiral curve of rather more than a circle;[297] in later times they were ornamented with foliage, and sometimes with statuettes, and were enamelled and jewelled. Numerous representations and actual examples exist; some may be seen in the South Kensington Museum. From early in the fourteenth century downward, a napkin of linen or silk is often found attached by one corner to the head of the staff, whose origin and meaning seem to be undetermined. The official costume of the remaining orders, together with the symbols significant of their several offices, are well brought out in the degradation of W. Sawtre, already given at p. 214.
