The name of Gerhard PODSKALSKY is well known to all Byzantinists and his works on Russian Christianity and theology (988–1237) and Greek theology (1453–1821) published by Beck in 1982 and 1988 respectively have become classic works of reference. Since both Bulgaria and Serbia were the Empire's immediate neighbours and at various times integral parts of the Byzantine Empire this book is of greater importance for the Byzantinist than the previous two and without any doubt it will find a place in every scholar's library. In his preface the author stresses (p. VII) that the book has been written with Western scholars in mind and for this reason he not only gives brief summaries of the contents of all original Slav works but also lists translations in Western languages of the works discussed, which makes the book invaluable for scholars who do not have a working knowledge of Slavonic and modern Slav languages.
