Byzantine Art

Please answer the questions by the given links.
Byzantine Art takes it’s name from the ancient city of Byzantium (formerly Constantinople, and today, Istanbul, Turkey). The Empire was the Eastern part of the old Roman Empire but Byzantine art is markedly different from Roman art.  After the Crusades, and sack of Constantinople by the Turks in 1453, the traditions of Byzantine Art ended up in Russia primarily.

By far, the most famous church to be built in the Early Empire period for the Emperor Justinian was Hagia Sophia (Church of Holy Wisdom in Greek).  The link above is from a much longer program – watch between 30:00- 35:42 (about 5 minutes) and summarize why it was built, who designed it (what were their backgrounds), and what did they do to construct such a massive dome – describe it USING THE VIDEO. How does the church reaffirm Justinian’s power?
In addition to mosaics, icons are another huge component of Byzantine art and religious tradition.  Icons are traditionally wood panels painted with the image of Christ, Mary, or other religious figures.  The word itself, from the Greek means image. The first link below is from an article describing the iconoclastic controversy during the Byzantine Empire – what was it? Why did it come about?  what was the counter argument for keeping the icons?  Then, watch the video (Questioning Religious Authority) – at what other times in history did iconoclasm, or image breaking, take place? Why?  The end of the video talks about the Baymian Buddhas – what is the irony surrounding their destruction?
