Lying on the hills under the old tower of the Rocca, of which nothing else remains, S. Miniato is itself, as it were, a weather-beaten fortress, that was, perhaps, never so beautiful as now, when no one keeps watch or ward. You may wander into the Duomo and out again into the cloistered, narrow streets, and climbing uphill, pass down into the great gaunt church like a fortress, S. Domenico, with its scrupulous frescoes, and though you will see many wonderful and some delightful things, it will be always with new joy you will return to S. Miniato herself, who seems to await you like some virgin of the centuries of faith, that age has not been able to wither, fresh and rosy as when she first stood on her beautiful hills. Yet unspoiled as she is, Otto I has dwelt with her, she was a stronghold of the Emperors, the fortress of the Germans; Federigo Barbarossa knew her well, and Federigo II has loved her and hated her, for here he spoke with poets and made a few songs, and here he blinded and imprisoned Messer Piero della Vigna, that famous poet and wise man, accusing him of treason.[84] Was it that he envied him his verses or feared his wisdom, or did he indeed think he plotted with the Pope? Piero della Vigna was from Capua, in the Kingdom; very eloquent, full of the knowledge of law, the Emperor made him his chancellor, and indeed gave him all his confidence, so that his influence was very great with a man who must have been easily influenced by his friends. Seeing his power, others about the Emperor, remembering Piero's low condition, no doubt sought to ruin him; and, as it seems, at last in this they were successful, forging letters to prove that the chancellor trafficked with the Pope. It was a time of danger for Frederick; he was easily persuaded of Piero's guilt, and having put out his eyes, he imprisoned him. Driven to despair at the loss of that fair world, Piero dashed his head against the walls of his prison, and so died. Dante meets him among the suicides in the seventh circle of the Inferno.
