'We begin to take up people ... the other day they seized an odd man who goes by the name of Count Saint-Germain. He has been here these two years, and will not tell who he is, or whence, but professes that he does not go by his right name. He sings, plays on the violin wonderfully, composes, is mad, and not very sensible. He is called an Italian, a Spaniard, a Pole; a somebody that married a great fortune in Mexico, and ran away with her jewels to Constantinople; a priest, a fiddler, a vast nobleman. The Prince of Wales has had unsatiated curiosity about him, but in vain. However, nothing has been made out against him; he is released, and, what convinces me he is not a gentleman, stays here, and talks of his being taken up for a spy.'

Here is our earliest authentic note on Saint-Germain; a note omitted by his French students. He was in London from 1743 to 1745, under a name not his own, but that which he later bore at the Court of France. From the allusion to his jewels (those of a deserted Mexican bride?), it appears that he was already as rich in these treasures as he was afterwards, when his French acquaintances marvelled at them. As to his being 'mad,' Walpole may refer to Saint-Germain's way of talking as if he had lived in remote ages, and known famous people of the past.

Having caught this daylight glimpse of Saint-Germain in Walpole, having learned that in December 1745 he was arrested and examined as a possible Jacobite agent, we naturally expect to find contemporary official documents about his examination by the Government. Scores of such records exist, containing the questions put to, and the answers given by, suspected persons. But we vainly hunt through the Newcastle MSS. and the State Papers, Domestic, in the Record Office, for a trace of the examination of Saint-Germain. I am not aware that he has anywhere left his trail in official documents; he lives in more or less legendary memoirs, alone.

At what precise date Saint-Germain became an intimate of Louis XV., the Duc de Choiseul, Madame de Pompadour, and the Maréchal de Belle-Isle, one cannot ascertain. The writers of memoirs are the vaguest of mortals about dates; only one discerns that Saint-Germain was much about the French Court, and high in the favour of the King, having rooms at Chambord, during the Seven Years' War, and just before the time of the peace negotiations of 1762-1763. The art of compiling false or forged memoirs of that period was widely practised; but the memoirs of Madame du Hausset, who speaks of Saint-Germain, are authentic. She was the widow of a poor man of noble family, and was one of two femmes de chambre of Madame de Pompadour. Her manuscript was written, she explains, by aid of a brief diary which she kept during her term of service. One day M. Senac de Meilhan found Madame de Pompadour's brother, M. de Marigny, about to burn a packet of papers. 'It is the journal,' he said, 'of a femme de chambre of my sister, a good kind woman.' De Meilhan asked for the manuscript, which he later gave to Mr. Crawford, one of the Kilwinning family, in Ayrshire, who later helped in the escape of Louis XVI. and Marie Antoinette to Varennes, where they were captured. With the journal of Madame du Hausset were several letters to Marigny on points of historical anecdote.[45]

Crawford published the manuscript of Madame du Hausset, which he was given by de Meilhan, and the memoirs are thus from an authentic source. The author says that Louis XV. was always kind to her, but spoke little to her, whereas Madame de Pompadour remarked, 'The King and I trust you so much that we treat you like a cat or a dog, and talk freely before you.'

As to Saint-Germain, Madame du Hausset writes: 'A man who was as amazing as a witch came often to see Madame de Pompadour. This was the Comte de Saint-Germain, who wished to make people believe that he had lived for several centuries. One day Madame said to him, while at her toilet, "What sort of man was Francis I., a king whom I could have loved?" "A good sort of fellow," said Saint-Germain; "too fiery—I could have given him a useful piece of advice, but he would not have listened." He then described, in very general terms, the beauty of Mary Stuart and La Reine Margot. "You seem to have seen them all," said Madame de Pompadour, laughing. "Sometimes," said Saint-Germain, "I amuse myself, not by making people believe, but by letting them believe, that I have lived from time immemorial." "But you do not tell us your age, and you give yourself out as very old. Madame de Gergy, who was wife of the French ambassador at Venice fifty years ago, I think, says that she knew you there, and that you are not changed in the least." "It is true, madame, that I knew Madame de Gergy long ago." "But according to her story you must now be over a century old." "It may be so, but I admit that even more possibly the respected lady is in her dotage."'

At this time Saint-Germain, says Madame du Hausset, looked about fifty, was neither thin nor stout, seemed clever, and dressed simply, as a rule, but in good taste. Say that the date was 1760, Saint-Germain looked fifty; but he had looked the same age, according to Madame de Gergy, at Venice, fifty years earlier, in 1710. We see how pleasantly he left Madame de Pompadour in doubt on that point.

He pretended to have the secret of removing flaws from diamonds. The King showed him a stone valued at 6,000 francs—without a flaw it would have been worth 10,000. Saint-Germain said that he could remove the flaw in a month, and in a month he brought back the diamond—flawless. The King sent it, without any comment, to his jeweller, who gave 9,600 francs for the stone, but the King returned the money, and kept the gem as a curiosity. Probably it was not the original stone, but another cut in the same fashion, Saint-Germain sacrificing 3,000 or 4,000 francs to his practical joke. He also said that he could increase the size of pearls, which he could have proved very easily—in the same manner. He would not oblige Madame de Pompadour by giving the King an elixir of life: 'I should be mad if I gave the King a drug.' There seems to be a reference to this desire of Madame de Pompadour in an unlikely place, a letter of Pickle the Spy to Mr. Vaughn (1754)! This conversation Madame du Hausset wrote down on the day of its occurrence.

Both Louis XV. and Madame de Pompadour treated Saint-Germain as a person of consequence. 'He is a quack, for he says he has an elixir,' said Dr. Quesnay, with medical scepticism. 'Moreover, our master, the King, is obstinate; he sometimes speaks of Saint-Germain as a person of illustrious birth.'
