 After the collapse of the Western Empire the study of Galen and other Greek works almost disappeared in the Latin West.In contrast, in the predominantly Greek-speaking eastern half of the Roman empire (Byzantium), many commentators of the subsequent centuries, such as Oribasius, physician to the emperor Julian who compiled a "Synopsis" in the 4th century, preserved and disseminated Galen's works, making Galenism more accessible.Nutton refers to these authors as the "medical refrigerators of antiquity".
