what is the main difference between the floor plans during the early christian and byzantine time
Early Christian art and architecture More complex and expensive works are seen, as the wealthy gradually converted, and more theological complexity appears, as Christianity became subject to acrimonious doctrinal disputes. At the same time a very different type of art is found in the new public churches that were now being constructed. Somewhat by accident, the best group of survivals of these is from Rome where, together with Constantinople and Jesusalem, they were presumably at their most magnificent. Mosaic now becomes important; fortunately this survives far better than fresco, although it is vulnerable to well-meaning restoration and repair. It seems to have been an innovation of early Christian churches to put mosaics on the wall and use them for sacred subjects; previously the technique had essentially been used for floors and walls in gardens. By the end of the period the style of gold background had developed that continued to characterize Byzantine images, and many Early Medieval Western ones.
