Early Christian Art
A notable feature in the Byzantine detail is the prevalence of the circle, frequently grouped in three, four and five, with the respective significance of the Trinity, the Evangelists and the Cross, or Five Wounds. The grotesques of the Pagan detail are conspicuously absent, giving place to forms more in keeping with the new religion, such, for instance, as the cross and the vine.

Mosaic work, either of marble or glass, constituted the decoration in such suitable positions as the floors, spandrils, lunettes and domes, gold being largely employed in the backgrounds. Windows, at times large in area, were glazed as in Roman times with cast slabs of glass, set in metal frames, usually bronze; and thin slabs of translucent marble and onyx were also used for glazing purposes.
