“The contempt of risk and the presumptuous hope of success are in no period of life more active than at the age at which young people choose their professions,” wrote Adam Smith in 1776. “How little the fear of misfortune is then capable of balancing the hope of good luck.”

When Booker T. Washington and Austrian ambassador Ladislaus Hengelmüller visited the White House on the same day in November 1905, Hengelmüller took Washington’s overcoat by mistake. According to the Washington Post, he noticed the mix-up on finding in the pocket “the left hind foot of a graveyard rabbit, killed in the dark of the moon,” which he “heroically relinquished.”

On Friday, January 13, 1882, thirteen men met in New York City as the Thirteen Club; they walked under a ladder, ate lobster salad sculpted into the shape of a coffin, and sat beneath a banner reading morituri te salutamus (“we who are about to die salute you”). The following year, the club’s newsletter gleefully reported that “not a single member is dead.” 

“The die,” wrote geographer Pausanias circa 150, “is the plaything of youths and maidens, who have nothing of the ugliness of old age.” 

Legend regarding the horseshoe as a lucky symbol holds that in the tenth century, while St. Dunstan was working in England as a farrier, the devil entered the forge and demanded his hooves be reshod. During the process, the future saint caused as much pain as he could, and the devil begged him to stop. Dunstan agreed—on the condition that Satan never enter a house where a horseshoe is on display.

In November 1934 a team of American baseball stars, including Babe Ruth, toured Japan. When they arrived for a game in the town of Narashino, each man was presented with a horseshoe-shaped flower wreath. Ruth detested the gift; he later told a Japanese baseball magazine that he considered such wreaths bad luck and had never hit a home run after receiving one.
