The Codex is an early 12 Century manuscript containing one of the earliest, most complete medieval commentaries on the Camino. It has five parts: The first is a liturgical collection of musically notated chants, sermons and readings for the celebration of the three feasts of St. James. The second is a collection of miracles attributed to St. James. The third relates the account of the transferal of St. James’ remains from the place of his death, in the Holy Land, to Spain. The fourth records the efforts of Charlemagne to push the Moors back out of Spain, and includes the death of Roland at Roncesvalles. The fifth section is a travelogue, listing the roads, landscape, sources of food and water along the way, with colorful, often hostile descriptions of the people and their customs that one passes on the route of the Camino.
