Greatraks accepted the invitation, and tried his manipulations and prayers upon Lady Conway. He failed, however, in affording any relief. The poor lady’s headache was excited by causes too serious to allow her any help, even from faith and a lively imagination. He lived for some months in Lord Conway’s house, at Ragley, in Warwickshire, operating cures similar to those he had performed in Ireland. He afterwards removed to London, and took a house in Lincoln’s-Inn Fields, which soon became the daily resort of all the nervous and credulous women of the metropolis. A very amusing account of Greatraks at this time (1665) is given in the second volume of the Miscellanies of St. Evremond, under the title of the Irish prophet. It is the most graphic sketch ever made of this early magnetiser. Whether his pretensions were more or less absurd than those of some of his successors, who have lately made their appearance among us, would be hard to say.
“When M. de Comminges,” says St. Evremond, “was ambassador from his most Christian majesty to the king of Great Britain, there came to London an Irish prophet, who passed himself off as a great worker of miracles. Some persons of quality having begged M. de Comminges to invite him to his house, that they might be witnesses of some of his miracles, the ambassador promised to satisfy them, as much to gratify his own curiosity as from courtesy to his friends; and gave notice to Greatraks that he would be glad to see him.
