2011 survey carolingian-ottonianKDaigrDuring the Carolingian and Ottonian periods from 800-1050, art aimed to renew and emulate the grandeur of the Roman Empire. Charlemagne commissioned works like the Coronation Gospels and his Palatine Chapel at Aachen that referenced classical forms. Monastic plans like St. Gall also spread standardized architectural designs. Under Bishop Bernward, Ottonian art at the Church of St. Michael's in Hildesheim featured bronze doors and columns with relief sculptures that told biblical stories and emulated Roman precedents like Trajan's Column.
Comparison between early christian and byzantine architectureNguyễn ViệtEarly Christian architecture emerged in the 3rd-7th centuries CE as Christianity gained prominence in the Western Roman Empire. Churches were modeled after Roman basilicas with flat roofs. Byzantine architecture developed later between 330-1453 CE in the Eastern Roman Empire after the capital moved to Constantinople. Byzantine churches had central, domed plans and decorative mosaics. They combined Roman traditions with Eastern influences like domes supported by pendentives. Mosaics depicted Christian figures and symbols and emphasized the relationship between church and imperial patronage in the Byzantine Empire.
