It was so with Machiavelli. I picture him at San Casciano as he lived in retirement upon his property after the fall of the Republic, perhaps with a twinge of the torture that punished his conspiracy still lurking in his limbs. Such twinges could not stop his dreaming. Then it was "The Prince" was written. All day he went about his personal affairs, saw homely neighbours, dealt with his family, gave vent to everyday passions. He would sit in the shop of Donato del Corno gossiping curiously among vicious company, or pace the lonely woods of his estate, book in hand, full of bitter meditations. In the evening he returned home and went to his study. At the entrance, he says, he pulled off his peasant clothes covered with the dust and dirt of that immediate life, washed himself, put on his "noble court dress," closed the door on the world of toiling and getting, private loving, private hating and personal regrets, sat down with a sigh of contentment to those wider dreams. 
I like to think of him so, with brown books before him lit by the light of candles in silver candlesticks, or heading some new chapter of "The Prince," with a grey quill in his clean fine hand.
