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.
