When 17-year-old polymath James Crichton arrived in Paris in 1578 to complete his education, he immediately challenged the faculty of the College of Navarre to a disputation. And he was pretty cocky about it:

He proposed that it should be carried on in any one of twelve specified languages, and have relation to any science or art, whether practical or theoretical. The challenge was accepted; and, as if to show in how little need he stood of preparation, or how lightly he held his adversaries, he spent the six weeks that elapsed between the challenge and the contest, in a continual round of tilting, hunting, and dancing.

“On the appointed day, however, and in the contest, he is said to have encountered all the gravest philosophers and divines, and to have acquitted himself to the astonishment of all who heard him. He received the public praises of the president and four of the most eminent professors. The very next day he appeared at a tilting match in the Louvre, and carried off the ring from all his accomplished and experienced competitors.”

(From Samuel Griswold Goodrich, Curiosities of Human Nature, 1852)

On the night of May 11, 1812, John Williams of Redruth in Cornwall awakened his wife and told her he’d dreamed that he was in the lobby of the House of Commons and saw a man shoot the chancellor. Twice he went back to sleep, and twice he had the same dream.

Williams repeated the experience to friends in the following days, one of whom told him, “Your description is not at all that of the Chancellor, but is certainly very exactly that of Mr. Perceval, the chancellor of the exchequer.” Williams was explaining that he had never met or corresponded with this man when a messenger arrived from Truro with word that Perceval had been shot by an assassin in the lobby of the House of Commons on May 11 — the night of Williams’ dream.

According to a contemporary news account, Williams visited the spot six weeks later: “Immediately that he came to the steps at the entrance of the lobby, he said, ‘This place is as distinctly within my recollection, in my dream, as any room in my house,’ and he made the same observation when he entered the lobby. He then pointed out the exact spot where Bellingham stood when he fired, and which Mr. Perceval had reached when he was struck by the ball, where, and how he fell. The dress both of Mr. Perceval and Bellingham agreed with the description given by Mr. Williams, even to the most minute particular.”

In 1923, 7-year-old Rosemary Brown said she’d had a vision of a white-haired man in a black gown. “He told me that when I grow up, he would give me music,” she said.

Ten years later she recognized a picture of Franz Liszt. And in 1964, she said he returned, acting “like sort of a reception desk” to put her in touch with dead composers from Grieg to Chopin, who dictated new works to her from beyond the grave.

The classical music establishment gave these mixed marks. Leonard Bernstein and André Previn were skeptical, but Richard Rodney Bennett said, “If she is a fake, she is a brilliant one, and must have had years of training.” (She claimed to have had only three years of piano instruction.) “Some of the music is awful, but some is marvelous. I couldn’t have faked the Beethoven.”

Whatever the truth, the experiment is over now. Brown died in 2001, presumably joining her illustrious friends — and depriving them of an audience here below.
