The Byzantine empire influenced the religion, writing, art and architecture of Russia.The Russians received the religion of Greek Orthodox which even eventually became Russian orthodox. The Russians received the Cyrillic alphabet, that they still use today, from the Byzantines. The style of art the Byzantines are famous for are mosaics. Mosaics are pictures or patterns produced by arranging together small colored pieces of hard material, such as stone, tile, or glass. The Byzantines influenced the Russians to start using this style of art.
