Explanation:

Byzantine art is an artistic expression that is configured from the fifteenth century, strongly rooted in the Hellenistic and Eastern world, as a continuation of early Christian art. Since the beginning of the fifth century, an own and differentiated artistic formal language has been created that is maintained in the Western Empire. The taste for the richness and ornamental sumptuousness of Byzantine art, eminently Aulic, required the cladding of the walls of its temples with mosaics, not only to hide the poverty of the materials used but also as a means to express religiosity and semi-divine character of imperial power. The pictorial representation in Byzantine culture and Eastern Christianity exerted a particularly important function since it was considered the materialization of the divinity (revelation of the divine or theophany), in some cases even with the consideration of "made by non-human hands".
