When Ernest Rutherford and Frederick Soddy discovered that with radioactivity one atom can be transformed into another, Soddy recalled blurting out “Rutherford, this is transmutation: the thorium is disintegrating and transmuting itself into argon gas.” As “the words seemed to flash through” Soddy “as if from some outside force,” Rutherford replied, “For Mike’s sake, Soddy, don’t call it transmutation. They’ll have our heads off as alchemists.”

A doctoral student in economics at Harvard University in 2004 compared the rise and fall of temperatures to the likelihood of witch trials in Europe, discovering that they often formed an inverse relationship. The average temperature between roughly 1520 and 1770 was two degrees lower than previous centuries, leading to crop failure and economic instability. The majority of trials and executions for witchcraft occurred during the period, known as the “little ice age.”

At a seance in the White House in 1862, Nettie Colburn Maynard, the medium, recalled that, after losing consciousness, she, channeling Daniel Webster, spoke for over an hour, during which President Abraham Lincoln was assured that the Emancipation Proclamation he had written but not signed would be “the crowning event of his administration and life” and that he needed to “stand firm” against dissenters. Arthur Conan Doyle later speculated that it “may have been one of the most important [moments] in the history of the United States.”

At the end of The Tempest, Prospero relinquishes his “rough magic” and declares, “I’ll break my staff,/Bury it certain fathoms in the earth,/And deeper than did ever plummet sound/I’ll drown my book.” In W.H. Auden’s “commentary” on the play, The Sea and the Mirror, Prospero says at the beginning, “Now, Ariel, I am that I am, your late and lonely master,/Who knows now what magic is:—the power to enchant/That comes from disillusion. What the books teach one/Is that desires end up in stinking ponds.”

In 1891 Erik Weisz began using the stage name Harry Houdini—the first name deriving from his nickname “Ehrie” and the surname from the great French magician Jean-Eugène Robert-Houdin, who himself had taken the surname from his wife, Josephe Cecile Eglantine Houdin, in order, he wrote, “to distinguish me from my numerous homonyms.”

One of the oldest extant terrestrial globes, dating from around 1510, the Lenox, is the only map known to use the phrase “here be dragons,” designating an area in Southeast Asia near to the island of Komodo, known for its large lizards. 

Some four hundred years after the death of Lucretius, Saint Jerome wrote the only existing biography of the philosopher, in two sentences, suggesting that Lucretius “was rendered insane by a love potion” and killed himself. In 1868 Alfred, Lord Tennyson wrote in “Lucretius” that the philosopher’s wife “dreaming some rival, sought and found a witch / Who brewed the philter which had power, they said, / To lead an errant passion home again. / And this, at times, she mingled with his drink, / And this destroyed him.”

The second of the 282 laws in the Code of Hammurabi, dating from the eighteenth century bc, states, “If a man charge a man with sorcery, and cannot prove it, he who is charged with sorcery shall go to the river; into the river he shall throw himself, and if the river overcome him, his accuser shall take to himself his house. If the river show that man to be innocent, and he come forth unharmed, he who charged him with sorcery shall be put to death.”

Charles Mackenzie, a fur trader in Missouri in 1805, noted that the local American Indians with whom he traded held a low opinion of Meriwether Lewis and William Clark’s party when it came through. “The Indians admired the air gun, as it could discharge forty shots out of one load,” Mackenzie reflected, “but they dreaded the magic of the owners. ‘Had I these white warriors in the upper plains,’ said the Gros Ventres chief, ‘my young men on horseback would soon do for them as they would do for so many wolves, for, there are only two sensible men among them, the worker of iron and the mender of guns.’” The “sensible men” in question included neither Lewis nor Clark.
