Rainerus de Pisis. Pantheologia. Nuremberg: Anton Koberger, 1477.
Purchased with funds provided by Mrs. Henry Yeager.
Although this third volume of a comprehensive theological encyclopedia is significant both for its content and as a good example of incunabula (15th century printing), it is most remarkable for its chained binding. The binding is one-quarter calf over beechwood boards, with five brass bosses and two iron bars that strengthen the boards. The ten-link iron chain was used to attach the book to a library shelf, a precursor of modern library security systems.
