The history of each individual pall is curious. On the morning of St Agnes's Day (January 21) in each year, two lambs are sent into Rome each in a basket, the baskets being slung over a horse's back. These lambs are chosen with special reference to whiteness and goodness. The horse is driven to the palace of the Pope, who comes to a window and makes the sign of the cross over the lambs, which are then conducted to the church of St Agnes without the walls. Here, gaily adorned with flowers and ribbons, they are brought up to the altar, and kept there till mass is sung. After mass (formerly at the _Agnus Dei_) the celebrant blesses the lambs, which are then handed over to the charge of the canons of St John Lateran, by whom they are sent back to the Pope. The Pope hands them on to the dean of his subdeacons, who delivers them up to a nunnery, where they are kept and fed. When they are shorn, the wool is woven by the nuns into palls. On the eve of the day of St Peter and St Paul these palls are taken to St Peter's, and there blessed after evensong, after which they are shut up in a silver-gilt box to wait till they are wanted for bestowal on a new archbishop. Each archbishop on election must go to Rome in person to receive the pall, unless prevented by serious obstacles—when the latter is the case it is solemnly sent to him by the Pope. He is not permitted to engage in any episcopal duty before receiving the pall; afterwards the vestment is worn only at High Mass on the following days: Nativity, St Stephen, St John, Circumcision, Epiphany, Palm Sunday, Maundy Thursday, Holy Saturday, Easter Sunday, Monday and Tuesday, Ascension, Pentecost, Feasts of the Virgin, Nativity of St John the Baptist, all days of Apostles, All Saints, Dedications of Churches, principal local feasts in the diocese, Consecrations of Bishops, Ordinations of Clergy, Feast of the local Dedication, and the Anniversary of the wearer's consecration. The Pope, however, wears the pall at all times when he says mass. The pall is the symbol of the archiepiscopal authority, therefore it may not be worn without express papal permission outside the limits of the jurisdiction of the archbishop.[57] When he dies, the pall is buried with him, but it is only placed on his shoulders if he be buried within his own province, otherwise it is folded and placed beneath his head.[58] The pall is the only vestment which may not be lent by one cleric to another. [Illustration: FIG. 13.] We now come to a singular point in the history of the pall, and one which has so far baffled ecclesiologists to explain. Although the pall is generally regarded as the peculiar emblem of archbishops, and seems to have been kept for their especial and peculiar use by the rites which we have described, yet a few favoured bishops have from very early times been entitled to wear this vestment. The bishoprics which possess this privilege are those of Autun, Bamberg, Dol, Lucca, Ostia, Pavia, and Verona.
