A copy of the Complete Works of Shakespeare, known as the Robben Island Bible, was used by apartheid-era ANC prisoners including Nelson Mandela. It was passed from cell to cell and read in secret. The books owner originally passed it around to collect signatures, to remember his time in prison. He asked all the leading prisoners to sign next to their favorite passages.
Beside the passage in Julius Caesar beginning, “Cowards die many times before their deaths” is Mandela’s signature and the date, December 16 1977.
