Others had it branded upon them with a hot iron; one pilgrim in the "Mirac. de S. Thomæ" of Abbot Benedict gives the obvious reason, that though his clothes should be torn away, no one should be able to tear the cross from his breast. At the end of the _Officium peregrinorum_, which we have described, we find a rubric calling attention to the fact, that burning the cross in the flesh is forbidden by the canon law on pain of the greater excommunication; the prohibition is proof enough that at one time it was a not uncommon practice. But when the pilgrim reached the Holy Land, and had visited the usual round of the holy places, he became entitled to wear the palm in token of his accomplishment of that great pilgrimage; and from this badge he derived the name of Palmer. How the palm was borne does not quite certainly appear; some say that it was a branch of palm, which the returning pilgrim bore in his hand or affixed to the top of his staff;[188] but probably in the general case it was in the shape of sprigs of palm sewn crosswise upon the hat and scrip. The Roman pilgrimage seems always to have ranked next in popular estimation to that of the Holy Land;[189] and with reason, for Rome was then the great centre of the religion and the civilization of Western Christendom. The plenary indulgence which Boniface VIII. published in 1300, to all who should make the Jubilee pilgrimage to Rome, no doubt had its effect in popularizing this pilgrimage _ad limina apostolorum_. Two hundred thousand pilgrims, it is said, visited Rome in one month during the first Jubilee; and succeeding popes shortened the interval between these great spiritual fairs, first to fifty, then to thirty-three, and lastly to twenty-five years. The pilgrim to Rome doubtless visited many shrines in that great Christian capital, and was entitled to wear as many signs; but the chief signs of the Roman pilgrimage were a badge with the effigies of St. Peter and St. Paul, the cross-keys, and the vernicle. Concerning the first, there is a grant from Innocent III. to the arch-priest and canons of St. Peter's at Rome,[190] which confirms to them (or to those to whom they shall concede it) the right to cast and to sell the lead or pewter signs, bearing the effigies of the Apostles Peter and Paul, with which those who have visited their threshold decorate themselves for the increase of their devotion and a testimony of their pilgrimage. Dr. Rock says[191] "that a friend of his has one of these Roman pilgrim signs, which was dug up at Launde Abbey, Leicestershire. It is of copper, in the shape of a quatrefoil, one and three-quarter inches in diameter, and has the cross-keys on one side, the other side being plain." An equestrian pilgrim represented in Hans Burgmaier's "Der Weise Koenige," seems to bear on his cloak and his hat the cross-keys. The vernicle was the kerchief of Veronica, with which, said a very popular legend, she wiped the brow of the Saviour, when he fainted under His cross
