Papal Medals
Although not precisely devotional in purpose, a very large number of Papal medals are commemorate ecclesiastical events of various kinds, often the opening and closing of the Holy Door in the years of Jubilee. The series begins with the pontificate of Martin V, in 1417, and continues to the present. Some types professing to commemorate the acts of earlier popes, e.g. the Jubilee of Boniface VIII, are reconstructions or fabrications of later date.
Nearly all the most noteworthy actions of each pontificate for the last five hundred years have been commemorated by medals in this manner, and some of the most famous artists such as Benvenuto Cellini, Carsdosso, and others have designed them. The family of the Hamerani, papal medalists from 1605 to about 1807, supplied most of that vast series, and are celebrated for their work.
