The Book of Wallon sets out the history of slavery in ancient Greece and in ancient Rome of the Republic era and is considered the main work on this issue in its actual completeness. Instead of Wallon's 3rd volume dealing with Christianity's relationship to slavery, the work of Westerman is given, continuing the history of slavery in Rome during the Empire era. In the introductory article by prof. A.V. Mishulin establishes the importance of the work of A. Wallon in the development of historiography in antiquity and at the same time gives an appropriate assessment of this work.
