The Pierpont Morgan Library is now known internationally as both a research center and museum providing visitors access to some of the Western world's most significant cultural artifacts. This publication affords its readers an inside view of these rich holdings, first assembled by a passionate, private collector, with informative essays on priceless illuminated manuscripts from the Middle Ages and Renaissance, on pre-1825 drawings by masters such as Rembrandt, Rubens, Piranesi, Fuseli, and Blake, on a unique collection of musical scores by Bach, Mozart, Beethoven, Cage, and others, and on manuscripts and letters by Zola, Picasso, and Einstein as well as other writers, artists, and scientists from the fifteenth to twentieth centuries.
