This volume presents in English translation the Slavonic version of Josephus Flavius’ Jewish War, long inaccessible to Anglophone readers, according to N.A. Mescerskij’s scholarly edition, together with his erudite and wide-ranging study of literary, historical and philological aspects of the work, a textological apparatus and commentary. The synoptic layout of the Slavonic and Greek versions in parallel columns enables the reader to compare their content in detail. It will be seen that the divergences are far more extensive than those indicated hitherto.
