claim to investiture with ring and crosier, and granted freedom of election to episcopal sees. On the papal side, it was conceded that the bishops should receive investiture with the sceptre, that the episcopal elections should be held in the presence of the emperor or his representatives, that in case of disputed elections the emperor should, after the decision of the metropolitan and the suffragan bishops, confirm the rightfully elected candidate, and lastly, that the imperial investiture of the temporal properties connected to the sees should take place in Germany before the consecration. In Burgundy and in Italy the imperial investiture would take place after the consecration ceremony, while in the Papal States the pope alone had the right of investiture, without any interference on the part of the emperor. As a result of this Concordat, the emperor still retained in his hands the controlling influence in the election of the bishops in Germany, though he had abandoned much in regard to episcopal elections in Italy and Burgundy. First Lateran Council To secure the confirmation of this Concordat of Worms, Calixtus II convened the First Lateran Council on 18 March 1123. It solemnly confirmed the Concordat and passed several disciplinary decrees, such as those against simony and concubinage among the clergy. Decrees were also passed against violators of the Truce of God, church-robbers, and forgers of ecclesiastical documents. The indulgences already granted to the crusaders were renewed, and the jurisdiction of the bishops over the clergy, both secular and regular, was more clearly defined. Later life, death and legacy Calixtus II devoted his last few years to re-establishing papal control over the Roman Campagna and establishing the primacy of his former prince-archbishopric, the See of Vienne over the long-time rival See of Arles. He also affirmed the authority of the bishop of Lyons over the church at Sens in France, transferred the historic bishopric of Mérida in Spain to Santiago de Compostela, and rebuilt the church of Santa Maria in Cosmedin in Rome. Calixtus died on 13 December 1124. A decade or two later, a French scholar (probably Aymeric Picaud) began composing a combination of miracle tales, liturgical texts and travelers guide relating to the increasingly popular pilgrimage route from southern France through northern Spain now called the Camino de Santiago. The work (published before 1173) was called the Liber Sant Jacobi (Book of St. James) or the Codex Calixtinus,
