Catholic Encyclopedia (1913)/Fanon
A shoulder-cape worn by the pope alone, consisting of two pieces of white silk ornamented with narrow woven stripes of red and gold; the pieces are nearly circular in shape but somewhat unequal in size and the smaller is laid on and fastened to the larger one. To allow the head to pass through there is made in the middle a round opening with a vertical slit running down farther. The front part of the fanon is ornamented with a small cross embroidered in gold.
The fanon is like an amice; it is, however, put on not under but above the alb. The pope wears it only when celebrating a solemn pontifical Mass, that is, only when all the pontifical vestments are used. The manner of putting on the fanon recalls the method of assuming the amice universal in the Middle Ages and still observed by some of the older orders (see AMICE). After the deacon has vested the pope with the usual amice, alb, the cingulum and sub-cinctorium, and the pectoral cross, he draws on, by means of the opening, the fanon and then turns the half of the upper piece towards the back over the pope's head. He now vests the pope with the stole, tunicle, dalmatic, and chasuble, then turns down that part of the fanon which had been placed over the head of the pope, draws the front half of the upper piece above the tunicle, dalmatic, and chasuble, and finally arranges the whole upper piece of the fanon so that it covers the shoulders of the pope like a collar.
The fanon is mentioned in the oldest known Roman Ordinal, consequently its use in the eighth century can be proved. It was then called anabolagium (anagolagium), yet it was not at that period a vestment reserved for the use of the pope. This limitation of its use did not appear until the other ecclesiastics at Rome began to put the vestment on under the alb instead of over it, that is, when it became customary among the clergy to use the fanon as an ordinary amice. This happened, apparently in imitation of the usage outside of Rome, between the tenth and twelfth centuries; however, the exact date cannot be given. But it is certain that as early as the end of the twelfth century the fanon was worn solely by the pope, as is evident from the express statement of Innocent III (1198-1216). The vestment was then called an orale; the name of fanon, from the late Latin fano, derived from pannus, (penos), cloth, woven fabric, was not used until a subsequent age. Even as early as the eighth century the pope wore the fanon only at solemn high Mass. The present usage, according to which the pope is vested, in addition to the fanon, with an amice under the alb, did not appear, at the earliest, until the close of the Middle Ages.
As to the form of the fanon and the material from which it was made in early times no positive information exists. Late in the Middle Ages it was made of white silk, as is shown by the inventory of the year 1295 of the papal treasure, as well as by numerous works of art; the favourite ornamentation was one of narrow stripes of gold and of some colour, especially red, woven into the silk. Up into the fifteenth century the fanon was square in shape; the present collar-like form seems to have appeared about the sixteenth century or even later.
