In a word, Byzantine culture is the pearl of medieval European culture, an important part of human cultural treasure house, and plays a connecting role in the history of western cultural development. Byzantine culture generally impacted the era of agricultural people in the world, protected the classical Greek and Roman cultural heritage from extinction, and made the classical culture spread to future generations. At the same time, the Byzantines adapted the classical culture to the life of medieval society and formed a special form of classical culture. Byzantine culture is rich in content, complete in system and high in development level, so it has played an active role in Central Europe where the cultural development is slow, directly promoted the civilization of the Slavic world, accelerated the development of Slavic countries, and formed the Eastern European world with the Orthodox Church as the core. Byzantine culture also had a positive impact on other cultures around it, and promoted the communication between different cultures in the Middle Ages. Byzantine culture provided western Europe in the late Middle Ages with progressive factors conducive to its future development, and its precious heritage in academic and artistic fields spread all over the world through various channels.
