Editing Pope Callixtus II (section)

==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, Spain|Mérida]] in Spain to [[Santiago de Compostela]], and rebuilt the church of [[Santa Maria in Cosmedin]] in Rome.<ref name="CE">{{Catholic |last=MacCaffrey |first=James |wstitle=Pope Callistus II |volume=3 |inline=1 |prescript=}}</ref>

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 [[James, son of Zebedee|St. James]]'') or the [[Codex Calixtinus]], since a letter introduction attributed to this pope preceded each of the five chapters. Several of his authentic letters have also been preserved.<ref name="CE"/>
