The Edelstein contained in this manuscript consists of 100 fables,
composed around 1330 by the Bernese Dominican Ulrich Boner; the
fables were taken from various Latin sources and were translated by
Boner into Swiss Dialect. The script and the typical
characteristics of the layout with spaces for never-executed
illustrations indicate a work from the late phase (approximately
about 1455-1460) of Diebold Lauber’s workshop in Hagenau in
Alsace, a work that had been prepared to be completed at the
request of a buyer.
