Theodore the Stoudite was one of the most influential Byzantine authors and ecclesiastical authorities, playing a prominent role in the defense of icons during the second period of the iconoclastic controversy (early ninth century). The present publication from the Dumbarton Oaks Medieval Library series translates for the first time into English three medieval Greek texts—the Life of Theodore of Stoudios by Michael the Monk, the Encyclical Letter of Naukratios, and the Translation and Burial of the Remains of Theodore of Stoudios and Joseph of Thessalonike—which, notwithstanding their different authorship, compositional date, and purposes, revolve around the life, contests, death, burial, and reburial of this ecclesiastical authority. The texts are given in the original with a facing English translation and are accompanied by an Introduction, Abbreviations, Note on the Texts, Notes to the Texts, Notes to the Translations, a Bibliography, and an Index. With this volume once again the Dumbarton Oaks Medieval Library series succeeds in advancing its mission, which is to offer to a wider audience (academic and lay) an engaging translation complemented by erudite notes that elucidate the three medieval Greek works’ textual witnesses and transmission history and analyze their context and content.
