Most of the art was abstract and stood for icons, and normally took the forms of small panels. These panels were all over churches a long with crosses and the amazing Architecture. Most of the structures for churches in the Byzantine Empire had domes and were surrounded by many figures from the bible. The dome represents the expansion of the heavens; the Orthodox Christians believed the heavens were always expanding to allow more people to enter. A lot of the churches had colored/abstract panels and beautiful stained glass windows. There were two different forms of architecture for churches found in this Empire.
The basilica type had a long column shaped tower that was covered with a wooden roof, which formed a dome at the top. The other type was the vaulted centralized church. This had separate components that gathered under a central dome. It was very important for the Orthodox churches to have a dome shaped top because of its significance to the heavens. In most of the churches there was a variety of different shapes incorporate into the windows and floors.
