Codex Calixtinus, 12th century illuminated manuscript
God, You called your servant Abraham from Ur in Chaldea, watching over him in all his wanderings, and guided the Hebrew people as they crossed the desert. Guard these your children who, for the love of your Name, make a pilgrimage to Compostela. Be their companion on the way, their guide at the crossroads, their strength in weariness, their defense in dangers, their shelter on the path, their shade in the heat, their light in the darkness, their comfort in discouragement, and the firmness of their intentions; that through your guidance, they may arrive safely at the end of their journey and, enriched with grace and virtue, may return to their homes filled with salutary and lasting joy.
"The Codex Calixtinus is a 12th-century illuminated manuscript formerly attributed to Pope Callixtus II, though now believed to have been arranged by the French scholar Aymeric Picaud. The principal author is actually given as 'Scriptor I'.
It was intended as an anthology of background detail and advice for pilgrims following the Way of St. James to the shrine of the apostle Saint James the Great, located in the cathedral of Santiago de Compostela, Galicia. The codex is alternatively known as the Liber Sancti Jacobi, or the Book of Saint James. The collection includes sermons, reports of miracles and liturgical texts associated with Saint James, and a most interesting set of polyphonic musical pìeces. In it are also found descriptions of the route, works of art to be seen along the way, and the customs of the local people."
