The stories of Falk's miraculous powers are too numerous to relate here, but a letter written by an enthusiastic Jewish admirer, Sussman Shesnowzi, to his son in Poland will serve to show the reputation he enjoyed: Hear, my beloved son, of the marvellous gifts entrusted to a son of man, who verily is not a man, a light of the captivity ... a holy light, a saintly man ... who dwells at present in the great city of London. Albeit I could not fully understand him on account of his volubility and his speaking as an inhabitant of Jerusalem.... His chamber is lighted by silver candlesticks on the walls, with a central eight-branched lamp made of pure silver of beaten work. And albeit it contained oil to burn a day and a night it remained enkindled for three weeks. On one occasion he abode in seclusion in his house for six weeks without meat and drink. When at the conclusion of this period ten persons were summoned to enter, they found him seated on a sort of throne, his head covered with a golden turban, a golden chain round his neck with a pendant silver star on which sacred names were inscribed. Verily this man stands alone in his generation by reason of his knowledge of holy mysteries. I cannot recount to you all the wonders he accomplishes. I am grateful, in that I am found worthy to be received among those who dwell within the shadow of his wisdom.... I know that many will believe my words, but others, who do not occupy themselves with mysteries, will laugh thereat. Therefore, my son, be very circumspect, and show this only to wise and discreet men. For here in London this master has not been disclosed to anyone who does not belong to our Brotherhood. The esteem in which Falk was held by the Jewish community, including the Chief Rabbi and the Rabbi of the new Synagogue, appears to have roused the resentment of his co-religionist Emden, who denounced him as a follower of the false Messiah and an exploiter of Christian credulity. Falk [he wrote in a letter to Poland] had made his position by his pretence to be an adept in practical Cabala, by which means he professed to be able to discover hidden treasures; by his pretensions he had entrapped a wealthy captain whose fortune he had cheated him out of, so that he was reduced to depending on the Rabbi's charity, and yet, despite this, wealthy Christians spend their money on him, whilst Falk spends his bounty on the men of his Brotherhood so that they may spread his fame. In general Falk appears to have displayed extreme caution in his relations with Christian seekers after occult knowledge, for the _Jewish Encyclopædia_ goes on to say: "Archenholz mentions a royal prince who applied to Falk in his quest for the philosopher's stone, but was denied admittance." Nevertheless Hayyum Azulai mentions (Ma'gal Tob, p. 13_b_):
