What was the role of the Byzantine Empire in the cultural development of Latin Europe during the Romanesque art period?

In Byzantium, almost all the works of ancient Greece were copied. In the imperial capital, ancient culture continued to be the foundation of school education. This Byzantine material was transferred to royal courts and throughout Europe from the 10th to the 12th century in the valleys of the Meuse and the Rhône, in Germany, and even in the kingdoms of Scandinavia.

The erudite Sylvain Gouguenheim, through this magnificent study, restores historical truth, crediting Byzantium for the transmission of ancient knowledge to the entire Western World.
