The present circular form originated in the tenth or eleventh century. Two excellent early examples of this form, belonging respectively to Archbishop St. Heribert (1021) and Archbishop St. Anno (d. 1075), are preserved in Siegburg, Archdiocese of Cologne. The two vertical bands of the circular pallium were very long until the fifteenth century, but were later repeatedly shortened until they now have a length of only about twelve inches. At first the only decorations on the pallium were two crosses near the extremities. This is proved by the mosaics at Ravenna and Rome. It appears that the ornamentation of the pallium with a greater number of crosses did not become customary until the ninth century, when small crosses were sewn on the pallium, especially over the shoulders. However, during the Middle Ages there was no definite rule regulating the number of crosses, nor was there any precept determining their colour. They were generally dark, but sometimes red. The pins, which at first served to keep the pallium in place, were retained as ornaments even after the pallium was sewn in the proper shape, although they no longer had any practical object. That the insertion of small leaden weights in the vertical ends of the pallium was usual as early as the thirteenth century is proved by the discovery in 1605 of the pallium enveloping the body of Boniface VIII, and by the fragments of the pallium found in the tomb of Clement IV.
