A story tells that after the death of Moses de Leon, a rich man of Avila named Joseph offered Moses' widow (who had been left without any means of supporting herself) a large sum of money for the original from which her husband had made the copy. She confessed that her husband himself was the author of the work. She had asked him several times, she said, why he had chosen to credit his own teachings to another, and he had always answered that doctrines put into the mouth of the miracle-working Shimon bar Yochai would be a rich source of profit. The story indicates that shortly after its appearance the work was believed by some to have been written by Moses de Leon.
