This illustrated catalogue presents detailed descriptions of nineteen Greek manuscripts acquired individually by the Library, during the twentieth century, and not previously described in any official Bodleian catalogue. The manuscripts vary widely in date and subject-matter. Some contain new discoveries, such as unpublished passages in a new manuscript of Philippos Monotropos' Dioptra (MS. Gr. th. d. 6), or the Greek translation of three prayers composed of quotations from St. Augustine's Confessions, which has come to light in a Horologion (MS. Gr. liturg. e. 8). Each entry contains a detailed description of the manuscript's textual contents, decoration, and physical features, and a full bibliography. This book will interest students of Greek texts (both secular and religious), as well as anyone with an interest in Byzantine and post-Byzantine culture.
