Pope Sixtus IV Appoints Bartolomeo Platina Prefect of the Vatican Library

1475 to 1481
John Willis Clark originally reproduced this black & white image of the fresco in the Vatican showing Sixtus IV with books elegantly bound laying on work desks.
John Willis Clark originally reproduced this black & white image of the fresco in the Vatican showing Sixtus IV with books elegantly bound laying on work desks. The books are so close together on the desks that there appears to be no space for anyone to open a book. This leaves the impression that they were arranged specially for this painting, and that ordinarily some of them might have been stored in a different way.

Under Pope Sixtus IV specific quarters were established to house the volumes of manuscripts and the archives that formed the nucleus of the Vatican Library. In 1475 the library prepared the first catalogue of its holdings as a manuscript for internal use in the library. About 1477 Sixtus IV appointed Bartolomeo Platina prefect of the library. In 1481 when Platina produced a listing of the library's holdings, the library held over 3,500 items, making it by far the largest in the Western world. 

Among his other accomplishments, Sixtus IV built the Sistine Chapel

The first study in English "On the Vatican Library of Sixtus IV" was by John Willis Clark, who is better known for his classic work, The Care of Books. Clark published his study of the earliest Vatican Library in the Proceedings of the Cambridge Antiquarian Society No. XLI (Being the 10th vol., 4th vol. of New Series) 11- 61, with three plates.
