When Albert Einstein visited Beno Gutenberg, a seismologist at Caltech, in 1933, the two strolled around the Pasadena campus while Gutenberg explained earthquake science. Suddenly their wives arrived to inform them there had been a massive earthquake. “We had become so involved in seismology,” recalled Gutenberg later, “that we hadn’t noticed.”

The destruction of Sodom and Gomorrah may have been caused by an earthquake that occurred through the Great Rift Valley around 1900 bc. The “brimstone and fire” described in the Bible would have been due to petroleum and gases present in the area igniting the cities.

According to sixth-century-bc Greek poet Hipponax of Colophon, in times of drought, famine, or plague an ugly or deformed person was chosen by the community to be pharmakós, or scapegoat. After being fed figs, barley cake, and cheese, he would be struck on the genitals with the bulbs and twigs of wild plants, led on a procession accompanied by flute, and burned on a pyre. His ashes were thrown into the sea. It is believed that Hipponax, whom Pliny the Elder once called “notoriously ugly,” may have been exaggerating the ritual.

Bibliophilic bishop Richard de Bury lamented the burning of the Library of Alexandria. “Who would not shudder at such a hapless holocaust, where ink is offered up instead of blood,” he wrote in 1344, “where the devouring flames consumed so many thousands of innocents?”

Accounts varied of the Great Famine of 1315–22, during which more than 10 percent of Europe’s population died. In Flanders: “Parents killed their children and children killed parents, and the bodies of executed criminals were eagerly snatched from the gallows.” In France: “There was no wine in the whole kingdom.”
