The Codex Bruce was bought during the 18th century by the famous traveller James Bruce in Upper Egypt. After his return to England, the text was copied with many errors and the original papyri badly bound, in some cases upside down and backwards. In this book, first published in 1933, Baynes corrects many of the earlier errors associated with this unusual Gnostic text, and includes over 120 plates with images of the original papyri and their transcription. Her translation is written in accurate yet readable English, and each page of translation is accompanied by expert commentary on this enigmatic meditation on nebulous Gnostic beliefs. This book will be of value to anyone interested in Gnosticism, Coptic epigraphy or the beliefs of early Christian heretics.
