The Mikraot Gedolot of Ben Hayyim, though hailed as an extraordinary achievement, was riddled with thousands of technical errors. Objections were also raised by the Jewish readership, based on the fact that the very first printing of the Mikra'ot Gedolot was edited by Felix Pratensis, a Jew converted to Christianity. Furthermore, Bomberg, a Christian, had requested an "imprimatur" from the Pope. Such facts were not compatible with the supposed Jewish nature of the work; Bomberg had to produce a fresh edition under the direction of acceptable Jewish editors. Nevertheless, this first edition served as the textual model for nearly all later editions until modern times. With regard to the Biblical text, many of Ben Hayyim's errors were later corrected by Menahem Lonzano and Shlomo Yedidiah Norzi.
