“Whom the gods love dies young,” wrote Menander in the late fourth century BC. “Whom the gods wish to destroy they first call promising,” Cyril Connolly noted over two millennia later.

Phia Rilke’s infant daughter had died a year before she gave birth to her son. She named him René Maria—sometimes referring to him as Fräulein, Margaret, and Sophie—and gave him dolls to play with, dressing him as a girl until he was six years old. The poet did not start using Rainer instead of René until he was in his twenties.

Paul Cézanne’s father, a banker, was fond of telling his son, “Young man, young man, think of the future! With genius you die, with money you live.” At least this is according to Émile Zola, who recalled the words of admonishment in one of his letters to his friend Paul. The two had first met as teenagers at boarding school in the 1850s.

“I went sailing up to Great Point, which is fourteen miles. It was fine and rough so we went out in the open ocean and shipped water grandly. I have bought a large swordfish sword for the agassiz of an old salt by the name of Judas,” Ernest Hemingway wrote to his brother Marcelline in one of his earliest known letters, shortly after his eleventh birthday, in 1910.

William Blake’s wife reminded the poet in old age, “You know, dear, the first time you saw God was when you were four years old, and He put His head to the window and set you a-screaming.” Allen Ginsberg said that in 1948, while a senior at Columbia University, he was visited by the voice of Blake, which revealed to him the power of poetry—this was after he had read one of Blake’s poems while masturbating.
