List of Illustrations Sources of The Illuminations: Photographic facsimile of pages from the manuscript of The Four Zoas, based on photographs (some infrared) provided by the Manuscript Room and Photograph Services of the British Library (to us through David V. Erdman), follow the numbering system still used by Erdman in The Complete Poetry and Prose of William Blake (1982) -and used throughout the text of this book; however, we note that Erdman has given a new ordering of pages (received as this book goes to press) in: Cettina Tramontano Magno and David V. Erdman, The Four Zoas by William Blake: A Photographic Facsimile of the Manuscript with Commentary on the Illuminations (Lewisburg: Bucknell University Press, 1987), and only in the following list can we give variations, in brackets. The pages from Edward Young's Night Thoughts, used to open sections (Regions) of this book and printed back to back with corresponding pages from The Four Zoas (for easy comparison), are taken from: Roger R. Easson and Robert N. Essick, William Blake: Book Illustrator: A Bibliography and Catalogue of the Commercial Engravings, Vol. I (Normal, Ill.: The American Blake Foundation, 1972), from Prof. Essick's copy of the plates.
