After he had been dismissed from government, and implicated in the anti-Medici conspiracy, Machiavelli was imprisoned, tortured, before returning to the family farm. But his passions ran deep.
…Machiavelli was unable to turn his mind from politics. ‘I could not help but fill your head with castles in the air,’ he wrote to Vettori in 1513, ‘because since Fortune has seen to it that I do not know how to talk about either the silk or wool trade, profits or losses, I have to talk about politics.’ He spent the days chewing the fat with woodcutters on the farm and playing cricca in the tavern. But in the evening, he told Vettori,
I return home and enter my study; on the threshold I take off my workday clothes, covered with mud and dirt, and put on the garments of court and palace. Fitted out appropriately, I step inside the venerable court of the ancients, where, solicitously received by them, I nourish myself on that food that alone is mine and for which I was born; where I am unashamed to converse with them … and they, out of their human kindness, answer me. And for four hours at a time I feel no boredom, I forget all my troubles, I do not dread poverty, and I am not terrified by death. I absorb myself into them completely. And because Dante says that: no one understands anything unless he retains [it], I have jotted down what I have profited from in their conversation and composed a short study, De principatibus.
