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

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

In this monumental study, Sylvain Gouguenheim restores historical truth, attributing credit to Byzantium for the transmission of ancient knowledge throughout the Western world.
