A signed letter from Niccolo Machiavelli has sold for £15,000 ($22,222) at Dreweatts & Bloomsbury in London, achieving an increase of 87.5% on an £8,000 estimate.
It dates to October, 1516 and is addressed to the head of the Papal navy. It references Machiavelli's visit to Livorno, Tuscany earlier that year.
Machiavelli was a Florentine diplomat and author who is best-known for his political treatise The Prince, which gained notoriety for its endorsement of immoral and underhand tactics.
The term "Machiavellian" is still used today.
