RARE FIRST EDITION of the first book on the teaching of language and literacy to deaf-mutes. Bonet advocated the necessity of reducing language to its phonetic units in order to teach the deaf to speak, and he developed his own system of finger-spelling, illustrated in the engraved plates. His ideas probably derived from the teachings of the Benedictine monk Pedro Ponce de Lon (1510-1584), a famous teacher of the deaf of whom no written works survive.
