In 1872, railroad magnate and racehorse owner Leland Stanford hired Eadweard Muybridge, then famous for his photographs of Yosemite Valley, to capture evidence on film that at a certain point in a horse’s trot, all four of its legs were simultaneously off the ground. Five years later, Muybridge developed a camera with a shutter speed of 2/1000 of a second, fast enough to prove Stanford correct. Muybridge went on a lecture tour with a device of his own design, the zoopraxiscope, which, through the rapid projection of photographic images, created the illusion of continuous movement.

Edith Wharton’s childhood German tutor, Anna Bahlmann, also taught her English and American literature; Norse, Greek, and Roman mythology; and history, art, and architecture. In 1878 Wharton called Bahlmann her “supreme critic” in a letter. Bahlmann is mentioned only four times in Wharton’s memoir and only once by name. One scholar suggested that Wharton’s “conviction about her intellectual and artistic isolation…compelled her to deny her closeness to her teacher.”
In March 2018 authorities in Alexandria, Egypt, began removing five hundred residents from their homes along the Al Mahmoudeya canal—dug in 1820 under orders from Viceroy Mohamed Ali—and into high-rises. “There are many areas,” says Alexandrian climate scientist Mohamed El Raey, “that are located at least three meters below sea level. They will have to be abandoned and the people relocated.” Estimates suggest near-term rise in sea levels will inundate a third of the city.
“Waters from snow and ice are all bad,” opined Hippocrates of Cos around 400 bc. “Once frozen, water never recovers its original nature, but the clear, light, sweet part is separated out and disappears.” Such melted waters, he declared, “are the worst for all purposes.”
A thirteenth-century Song dynasty text about commerce describes dangers faced by pearl divers, who sometimes fell prey to “huge fishes, dragons, and other sea monsters” that would rip open their stomachs or bite off their feet. A pearl was considered most valuable if perfectly round; the test was “that it will not cease rolling about all day when put on a plate.” To avoid heavy export duties, foreign traders sometimes concealed pearls in canes or umbrella handles.
The astronomer and mathematician Thales of Miletus is believed to have been the first ancient Greek scholar to discuss the phenomenon of magnetism. Aristotle notes in On the Soul that Thales held the belief that “the magnet has a soul in it because it moves the iron.” Five and a half centuries later, Diogenes Laërtius concurred with Aristotle, observing that Thales “attributed a soul or life even to inanimate objects.”
A 1551 municipal law in Lisbon regulated water at the Palacete Chafariz d’el Rei, segregating access across six spouts: the first for “slaves, freedmen, black people, mulattoes, and Indians”; the second for galley slaves; the fifth for “black and mulatto women and Indian women, both freed and captive”; and the sixth for white women and girls. White men and boys got the middle spouts, the third and the fourth.
A fourteenth-century-bc peace treaty recorded on a cuneiform tablet contains an invocation to Mithra, the Indo-Iranian god of the sun as well as of oaths and mutual obligation. In the Roman Empire, Mithras was honored as the god of loyalty to the emperor, while in Indian Vedic texts, he represents friendship and benevolence and, along with the god Varuna, is entrusted with the maintenance of the gods’ essence.
After “a certain knight shamefully divulged the intimacies and the secrets” of his lover, André Le Chapelain wrote in his late twelfth-century The Art of Courtly Love, an ad hoc tribunal of noble Gascon women “decided unanimously that forever after he should be deprived of all hope of love, and that in every court of ladies or of knights he should be an object of contempt and abuse to all.”
“Man is the only being that knows death; all others become old, but with a consciousness wholly limited to the moment which must seem to them eternal. We are time,” writes Oswald Spengler in The Decline of the West.
While at war to end Sparta’s regional supremacy, Theban general Epaminondas persuaded his soldiers to fight an extra four months, in violation of law; for this he was condemned to death on returning home victorious. He made no defense but proposed an inscription be made clarifying that “Epaminondas was punished by the Thebans with death” because “he not only saved Thebes from destruction but also secured freedom for all Greece.” The jury broke into laughter and refused to carry out the sentence.
Greek geographer Strabo wrote around 20 bc that, to deal with “a crowd of women” or “any promiscuous mob,” one cannot use reason but rather must exert control using myths and marvels. “For thunderbolt, aegis, trident, torches, snakes, thyrsus lances—arms of the gods—are myths,” he wrote. “The founders of states gave their sanction to these things as bugbears wherewith to scare the simpleminded.”
Scholars in the 1970s compiling the first comprehensive Sumerian dictionary struggled to interpret a phrase that translated into English as “He put a hot fish in her navel.”
Hatches of Rocky Mountain locusts (Melanoplus spretus) in 1874 and 1875 brought swarms up to 1,800 miles long and 110 miles wide across the Great Plains. Numbers were estimated in the trillions. Farmers risked starvation. The swarm is believed to have been the largest mass of living insects ever witnessed by modern man—but within thirty years the species disappeared. “I can’t believe M. spretus is extinct,” said ecologist Dan Otte in 2014. “But where to look for it?”
Suetonius, a biographer of Roman emperors, claimed that the violent ruler Tiberius had a clifftop location in Capri from which he liked to watch his victims thrown into the sea. “A party of marines were stationed below,” Suetonius wrote, “and when the bodies came hurtling down, they whacked at them with oars and boathooks, to make sure that they were completely dead.”
