Another famous manuscript preserved in the archives of Santiago Cathedral since the twelfth century is the priceless Codex of Calistus II., the date of which is supposed to be a few years later than that of the _Historia Compostelana_ (about 1140). This document, of which the capitals are illuminated, contains some curious miniatures, one having for its subject the departure of Charlemagne for Spain. Here there is a description of the principal roads by which pilgrims were wont to reach Santiago. Pope Calistus II. was one of the most illustrious of all the pilgrims who visited Santiago. He undertook the pilgrimage when he was an archbishop in France, about 1109. There are in existence three examples of this manuscript which bears his name: one is in the Royal Library at Madrid, and another, preserved in one of the other libraries, is a Gallegan translation dating from the first half of the fifteenth century. At the end of the twelfth century there was in existence a French translation. In the year 1173, Arnaldo del Monte, a monk of the celebrated monastery of Ripoll in the province of Gerona, went on a pilgrimage to Santiago. He handled, described, and made extracts from the precious Codex; his dedication of it is still preserved in the library of Ripoll, and there is also said to be a copy in the Paris library. The Codex of Calistus III., supposed to have been partly written by his chancellor, Aimerico Picard, is in five books. The first contains four homilies of Calistus on the three great festivals of Santiago, and the Mass, with a dramatic liturgy set to music composed by Fulbert de Chartres, retouched by the hand of Calistus or some other personage; some of the writings of Augustine, Ambrose, Jerome, and, we are told, of Bede, _per totum annum legenda_. The second contains “The Miracles of the Apostles”; the third gives an account of the translation of St. James from Jerusalem to Spain; the fourth, “How Charlemagne brought Spain under the yoke of Christ”; and the fifth, various writings.
