This brief but poignant study examines the key features of Byzantine Christianity from the 4th to the 15th centuries. Fabulously illustrated throughout, it covers a wide variety of subjects including: the structure of the Byzantine Church; liturgy and daily worship; doctrine; monasticism; icons and iconoclasm; architecture, art, and iconography; relations with the western church; and mission and expansion. The book ends by assessing the lasting legacies of the Byzantine Church, especially in the areas of liturgy, spirituality, and art.
