Pietro della Vigna (also Pier delle Vigne, Petrus de Vineas or de Vineis; Capua, ca. 1190 – San Miniato, 1249) 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 and blinded, committing suicide soon after.[1] He appears as a character in the Inferno of the Divine Comedy by Dante Alighieri.
