Italian church art in the Middle Ages included frescoes and mosaics which were mainly architectural in nature. Color and gold leaf were very popular at this time.
Five facts that I thought were interesting about Roman mosaics are that the design of how the tesserae will be laid out is scratched into a thin layer of mortar first, then the tesserae were placed on the mortar, following the pattern. Also, sometimes to make the mosaics very strong, they made a foundation out of broken stones and gravel, then put the mortar down and laid the tesserae out. Another fact I thought was interesting is that the way they designed mosaics is they had books called "pattern books" that had some designs to choose from. Sadly, none have survived. A fourth fact is that Roman mosaic artists almost never signed their work. Lastly, some of the first mosaics were made from colored rocks and pebbles instead of tesserae.
Astrological symbols figure prominately in Roman mosaics.
Mosaics (apex)
the ancient Romans who made floor mosaics had a great supply of marble so they used that but they made so many that they saved the other type of rock for makeing more important things
Mosaics created the art that fills the churches .

San Vitale Byzantine church
Italy
It is a beautiful church in the Vatican in Rome. It holds the popes, art, and mosaics.
The mosaics of Justinian and Theodora in the Church of San Vitale depict the emperor and empress flanked by clerical figures, illustrating the close relationship between religious and political authority in the Byzantine Empire. The mosaics emphasize the idea of theocracy by showing the rulers receiving divine approval and legitimacy for their reign from the church. The images convey the concept that the emperor's power is derived from God and that the church plays a central role in supporting and sanctioning his rule.
Roman mosaics were natural and realistic while Byzantine mosaics were meant to be symbolic.
They are just for decoration like in a Church there are tinted windows same in a Mosque the house of Allah has to be beautiful.
