Until the adoption of Christianity by Constantine Christian art derived its style and much of its iconography from popular Roman art, but from this point grand Christian buildings built under imperial patronage brought a need for Christian versions of Roman elite and official art, of which mosaics in churches in Rome are the most prominent surviving examples. Christian art was caught up in, but did not originate, the shift in style from the classical tradition inherited from Ancient Greek art to a less realist and otherworldly hieratic style, the start of gothic art.
Heavily influenced by sculpture, Gothic painters were also busy creating works of religious art, but not inside churches, where enormous stained glass windows now provided the colour and Biblical illustration that previously had been provided by murals: see, for instance, the translucent stained glass art inside Chartres Cathedral (c.1194-1250). Instead Gothic painters focused on illuminated manuscripts, such as the French Bibles Moralisees (c.1230-40), Le Somme le Roi (1290), the Manesse Codex (1310), Heures de Jeanne d'Evreux (1328), Psaltar of Bonne of Luxembourg (1349), the English Amesbury Psalter (1240), Queen Mary Psalter (1330) and the Arundel and Luttrell Psalters (1340). These are just a few of the many Books of Hours, Missals, Psalters, Apocalypses, Bibles and other illuminated gospel texts that emanated from monastic scriptoria of the period. See, in particular, works by Jean Pucelle (1290-1334). For more, see: History of Illustrated Manuscripts (600-1200). Christian Canvas Art
Only one major innovative example of Christian church architecture was built in Europe during the 19th century - the Sagrada Familia, Barcelona (1883), designed in a highly decorative neo-Gothic style by Antoni Gaudi. Celebrating the Holy Family and the mysteries of the Catholic faith, this extraordinary church with its tree-like formation of vaulted structures includes five towers and twelve campaniles. Made of stone and concrete, the building is embellished in parts with ceramic tiles, pompom finials and numerous sculptures, but is still not completely finished. Gaudi himself was inspired by the Arts and Crafts movement and was associated with the Catalan Modernista school. Christian Wall Art
