This is an excellent buy for the serious amateur history buff, especially those interested in the interplay of medieval religious and political factions in 14th century Europe. Meyendorff does a superb job of describing how Byzantium maintained its political influence despite its declining economic and military prowess. His focus is on Constantinople, but the intrigues of Russia, Lithuania and to a lesser extent Poland in the struggle for supremacy in Great and Little Russia are described also. He also deftly describes the ecclesiastical tension between the Papacy and the increasingly authoritarian Patriarch in the "Second Rome." For the price, this is one of the better buys out there for a medieval history afficionado.
