Delmedigo found it to his advantage, in order to give himself the appearance of a distinguished character in Poland, to shroud himself in silence and seclusion. He at first answered Serach's questions not personally, but through one of his companions, an assistant and follower, Moses Metz. This man described his teacher as a choice intellect, a demi-god, who carried in his brain all human and divine knowledge. He sketched his appearance and character, his occupation and behavior, regulated, as he said, by higher wisdom, gave information about his descent from a learned and distinguished family on his father's and his mother's side, and, as his teacher's mouth-piece, imposed upon the credulous Karaite by saying that he had composed works on all branches of knowledge, at which the world would be astonished, if they came to light. Metz also communicated to Serach some of his teacher's theories in mathematics, religion, and philosophy, and thus still more confused Serach's mind. In his communications on Judaism, which Delmedigo either made himself or through Moses Metz, he was very cautious; here and there, it is true, he allowed a suggestion of unbelief to glimmer through, but quickly covered it over with a haze of orthodoxy. Only where he could do so without danger Delmedigo expressed his real opinion. When he at last sent the Karaite an answer to a letter with his own hand (about 1621), he did not conceal his true views, but declared his preference for Karaism and its ancient teachers, loaded them undeservedly with praise, exalted science, and ridiculed the delusions of the Kabbala and its adherents. In the same letter to Serach, Delmedigo indulged in scoffs against the Talmud, and thought the Karaites fortunate that they were able to dispense with it. He had nothing to fear when he unburdened his heart before his Karaite admirer.
