Pier della Vigna: Circle 7, Inferno 13   Like Dante, Pier della Vigna (c. 1190 - 1240) was an accomplished poet--part of the "Sicilian School" of poetry, he wrote sonnets--and a victim of his own faithful service to the state. With a first-rate legal education and ample rhetorical talent, Pier rose quickly through the ranks of public service in the Kingdom of Naples and Sicily, from scribe and notary to judge and official spokesman for the imperial court of Frederick II. But his powers appear to have exceeded even these titles, as Pier claims to have had final say over Frederick's decisions (Inf. 13.58-63). While evidence of corruption casts some doubt on Pier's account of faithful service to the emperor, it is generally believed that he was indeed falsely accused of betraying Frederick's trust by envious colleagues and political enemies (Inf. 13.64-9). In this way, Pier's story recalls that of Boethius, author of the Consolation of Philosophy, a well known book in the Middle Ages (and a favorite of Dante's) recounting the fall from power of another talented individual falsely accused of betraying his emperor. Medieval commentators relate that Frederick, believing the charges against Pier (perhaps for plotting with the pope against the emperor), had him imprisoned and blinded. Unable to accept this wretched fate, Pier brutally took his life by smashing his head against the wall (perhaps of a church) or possibly by leaping from a high window just as the emperor was passing below in the street.   Pier's name--Vigna means "vineyard"--undoubtedly made him an even more attractive candidate for Dante's suicide-trees. As an added part of the contrapasso for the suicides, the souls will not be reunited with their bodies at the Last Judgment but will instead hang their retrieved corpses on the trees (Inf. 13.103-8).
