Synonymous with 'pastoral staff' is the word _crozier_ or _crosier_; but it is frequently ignorantly applied to a totally different object—the cross-staff borne before an archbishop. The statements which we so often see in works professing to treat on ecclesiological subjects as to the pastoral staff being crook-headed and borne by bishops, the crozier cross-headed, and borne (instead of the pastoral staff) _by_ archbishops, are derived from a misunderstanding of the evidence of mediaeval monuments.[71] The truth is, that the pastoral staff, with which the crozier is identical, is borne by bishops and archbishops alike; but archbishops are distinguished from bishops by having a staff, with a cross or crucifix in its head, borne _before_ them in addition. In many monuments, it is true, archbishops are represented as carrying the cross-staff, as, for instance, the brass of Archbishop Cranley in New College, Oxford; but it was obviously impossible in a monument of this kind to represent a cross-bearer preceding the archbishop, and the slight inaccuracy was, therefore, perpetrated of making the archbishop bear his own cross, thereby substantiating the evidence of the _pall_, that the person represented was of higher rank than that of a bishop. It was better managed at Mayence, where, in the monument of Albrecht von Brandenburg, 1545, figured above (p. 101), the figure is represented as bearing both the crozier and the cross-staff, one in each hand; and at Bamberg, in the cathedral of which city is a brass to Bishop Lambert von Brunn[72] (1399), wherein he is represented holding the crozier in his left hand, the cross-staff in his right. In the earliest representations of a staff of office there is a considerable variety in the shape of the head; knobs, crooks, and even Y-shapes, all meet us. The shape probably depended on the shape of the branch of the tree from which the staff was cut, much as does the shape of an ordinary walking-stick. By St Isidore's time, however, the crook-head had become stereotyped; the number of exceptional forms which we find after that date is small. There is a considerable number of staves of about the eleventh century, either represented on monuments or actually existing, of which the heads are tau-shaped; these possibly betray Eastern influence. A few effigies or pictures of bishops remain with a knob-headed staff; an example is to be seen in a ninth-century Anglo-Saxon pontifical at Rouen. [Illustration] The crook-headed staff is, however, by far the commonest, and after the eleventh century the only, form in which the bishop's crozier is found. Some variety is discoverable in the extent to which the staff is crooked. In some—notably in Irish specimens—the head is shaped like an inverted U, the form of the whole staff being that represented in the annexed diagram; but in the great majority of instances the head is recurved into a spiral or volute.
