The Afiigia NatuntlLs in 4 books is quite a different work from that in 20 books, containing far more occult and 

 superstitious matter than the latter, which made it however more acceptable to the contemporary reader. The author 

 mentions therein the camera obscura without the lens, the discovery of which is generally ascribed to Leonardo da Vincl. 

 but was really first mentionetl by Levi ben Gerson in a work translated in a.d. 1342 under the title ' De Sinibus et Cordis.* 

 The camera with the lens was first described in the work rewritten in 20 books.
