I went to look for the “Alchemist who travels time” and I found reccords of the Count of St. Germain.On the page, they say it’s indeed the man Hoshino was inspired about
There’s some interesting things in the wikipedia page of that man…
The Comte de Saint Germain (Born ~ 1691 died 27 February 1784) was a European adventurer, with an interest in science and the arts. (…)
In order to deflect inquiries as to his origins, he would invent fantasies, such as him being 500 years old
“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 that he is not a gentleman, stays here, and talks of his being taken up for a spy”
Walpole concludes that the Count was ‘”a man of Quality who had been in or designed for the Church. He was too great a musician not to have been famous if he had not been a gentleman'” Walpole describes the Count as pale, with 'extremely black’ hair and a beard. '”He dressed magnificently, [and] had several jewels’ and was clearly receiving 'large remittances, but made no other figure”’.
A mime and English comedian known as Mi'Lord Gower impersonated St. Germain in Paris salons. His stories were wilder than the real Count’s (he had advised Jesus, for example). Inevitably, hearsay of his routine got confused with the original.
“St. Germain gave himself out for a marvel and always aimed at exciting amazement, which he often succeeded in doing. He was scholar, linguist, musician, and chemist, good-looking, and a perfect ladies’ man. For a while he gave them paints and cosmetics; he flattered them, not that he would make them young again (which he modestly confessed was beyond him) but that their beauty would be preserved by means of a wash which, he said, cost him a lot of money, but which he gave away freely.”
“This extraordinary man, intended by nature to be the king of impostors and quacks, would say in an easy, assured manner that he was three hundred years old, that he knew the secret of the Universal Medicine, that he possessed a mastery over nature, that he could melt diamonds, professing himself capable of forming, out of ten or twelve small diamonds, one large one of the finest water without any loss of weight. All this, he said, was a mere trifle to him. Notwithstanding his boastings, his bare-faced lies, and his manifold eccentricities, I cannot say I thought him offensive. In spite of my knowledge of what he was and in spite of my own feelings, I thought him an astonishing man as he was always astonishing me.”
Myths, legends and speculations about St. Germain began to be widespread in the late 19th and early 20th centuries, and continue today. They include beliefs that he is immortal, the Wandering Jew, an alchemist with the “Elixir of Life”, a Rosicrucian, and that he prophesied the French Revolution.
[He is still claimed to have been seen since then, up ‘till 2004]
This is fascinating…
