This book makes available for the first time in English important works by the anti-Chalcedonian historian and biographer John Rufus on Peter the Iberian, Theodosius of Jerusalem, and Abba Romanus, three key figures of the Christian history of Palestine in the fifth and early sixth centuries C.E. The work offers a new critical edition of the Syriac text; the first-ever published English translation; a substantial introduction to Palestinian monasticism, the christological controversies of the time, and the life and writings of John Rufus; and ample annotations to a Syriac text whose Greek original is no longer available. By providing access to the Christian landscape (literally and metaphorically) in late antique and early Byzantine times, this volume offers a valuable counterbalance from a minority perspective to the biographical and historical writings of the Chalcedonian apologist Cyril of Scythopolis. Paperback edition is available from the Society of Biblical Literature (www.sbl-site.org)
