Byzantine art refers to the artistic style that developed in the Byzantine Empire, which lasted from the 4th to the 15th century. This art is characterized by its religious themes, particularly in Christian iconography, and often features vibrant colors, gold backgrounds, and intricate mosaics. Artists aimed to convey spiritual messages rather than realistic representations. Mosaics and frescoes were common forms of Byzantine art, often found in churches and public buildings. The use of flat, elongated figures and a lack of perspective created a sense of otherworldliness. Notable examples include the mosaics in the Hagia Sophia and the Church of San Vitale.
