Jacob ben Hayyim ibn Adonijah, having collated a vast number of manuscripts, systematized his material and arranged the Masorah in the second Bomberg edition of the Bible (Venice, 1524-25).
Next to Ibn Adoniyah, the critical study of the Masorah has been most advanced by Elia Levita, who published his famous "Massoret ha-Massoret" in 1538.
