 The unique manuscript in Toledo bears the name of Menahem ben Benjamin in its signature.It is uncertain whether the word used there, ("finished"), refers to the composition or to the copying of the work.This signature is also in rhymed prose; and it seems probable that at least part of page 132 (lines 12-23) in Neubauer's edition is by Menahem and not by Ahimaaz, for it contains an account of the author in language that one would not expect an author to use of himself.
