I extract the following story from Edmond Werdet's Histoire du Livre."[1] [1] "Histoire du Livre en France," par E.Werdet.8vo, Paris, 1851.
"The Poet Boccaccio, when travelling in Apulia, was anxious to visit the celebrated Convent of Mount Cassin, especially to see its library, of which he had heard much.

He accosted, with great courtesy, one of the monks whose countenance attracted him, and begged him to have the kindness to show him the library.

'See for yourself,' said the monk, brusquely, pointing at the same time to an old stone staircase, broken with age.

Boccaccio hastily mounted in great joy at the prospect of a grand bibliographical treat.

Soon he reached the room, which was without key or even door as protection to its treasures.
