Conversely, Elijah Delmedigo (c.1458 – c.1493), in his "Bechinat ha-Dat" endeavored to show that the Zohar could not be attributed to Shimon bar Yochai, by a number of arguments. He claims that if it were his work, the Zohar would have been mentioned by the Talmud, as has been the case with other works of the Talmudic period; he claims that had bar Yochai known by divine revelation the hidden meaning of the precepts, his decisions on Jewish law from the Talmudic period would have been adopted by the Talmud, that it would not contain the names of rabbis who lived at a later period than that of bar Yochai; he claims that if the Kabbalah was a revealed doctrine, there would have been no divergence of opinion among the Kabbalists concerning the mystic interpretation of the precepts.
