In 2014 Amelia Hamrick, an undergraduate at Oklahoma Christian University, noticed musical notes written across the buttocks of one of the denizens of hell depicted in Hieronymus Bosch’s painting The Garden of Earthly Delights. She transcribed it into modern notation and made a recording she posted on her blog. “So yes,” she wrote, “this is literally the 600-year-old butt song from hell.” The post went viral.

In her journal about life as a lady-in-waiting at Heian court, Sei Shonagon expresses her delight in men who keep a transverse flute tucked away in the breast of their robes. “There really is nothing more marvelous,” she writes. “And it’s delightful to discover beside your pillow at daybreak the handsome flute that your lover has inadvertently left behind him.”

Before the nineteenth century, a conductor’s baton was a baseball-bat-size implement that was banged against the floor to keep time. This could be dangerous. In 1687, while conducting a symphony playing Te Deum for Louis XIV, who had just recovered from serious illness, composer Jean-Baptiste Lully accidentally struck his foot with his baton, causing inflammation in his toe. He refused amputation, and an infection spread, killing him two months later.

Beware a comet “if it resembles a flute,” Pliny the Elder warned; “it portends something unfavorable related to music.” The Roman author did not offer further particulars.
