The author is Helen Gould Sheppard Professor of Art History at New York
University, Institute of Fine Arts, and a leading authority on English
medieval manuscript illumination. This volume bring together twenty-six
of Professor Sandler's studies, focusing on illustrated manuscripts
produced in England in the thirteenth and fourteenth centuries,
particularly on the illuminated psalters. The marginal illustrations in
these psalters are a topic of particular interest, and there are a
number of iconographic studies derived from this material. A separate
section deals with the illustrated encyclopedias of the period,
particularly the Omne bonum.
