Giorgio Colli was an Italian philosopher, philologist and historian. A native of Turin, he taught ancient philosophy at Pisa's university for thirty years; he edited and translated Aristotle's Organon and Kant's Critique of Pure Reason for Einaudi, a major publishing house in Italy. Subsequently, he produced the first complete edition of Nietzsche's work together with his friend Mazzino Montinari. His work culminated in La Sapienza greca, an edition and translation of the "Presocratics". Interrupted by his death in 1979 in Fiesole, it was supposed to be in eleven volumes. Vikipedi
