Pietro della Vigna (ca 1190 - 1249)

Pietro della Vigna (also Pier delle Vigne, Petrus de Vineas or de Vineis) was an Italian jurist and diplomat, who acted as chancellor and secretary (logothete) to Emperor Frederick II. Falsely accused of lèse-majesté, he was imprisoned, blinded and committed suicide soon after. He appears as a character in the Inferno of the Divine Comedy by Dante Alighieri.
