Giacomo Casanova's Chunk of Black Marble

Origin
Giacomo Girolamo Casanova (1725 - 1798) was an Italian adventurer and author of the Republic of Venice. At thirty Casanova was arrested for the affront to religion and common decency. The Leads was a prison of seven cells on the top floor of the east wind of the Doge's palace, reserved for prisoners of higher status as well as certain types of offenders-such as political prisoners, defrocked or libertine priests or monks. Without a trial Casanova was sentenced to five years imprisonment. During exercise walks he was granted in the prison garret, he found a piece of black marble and an iron bar which he smuggled back to his cell; he hid the bar inside the armchair in his cell. When he was without cell mates he sharpened the bar into a spike with the stone. Gouging through the floor he was moved before his initial escape. Hiding it into a book he gave the bar to the prisoner across the hall who used the spike to escape into the ceiling, cross over to Casanova and let him free as well. The two escaped across the rooftops and then by a gondola behind the palace.
