In autumn, 1465, two humanists agreed to have a battle. Lorenzo Guidetti was a disciple and friend of Cristoforo Landino, the most prominent teacher of rhetoric in the Florentine Studio. Buonaccorso Massari was a pupil of a less famous master, Giovanni Pietro of Lucca. Naturally, Massari began the fight, with all the pretended friendliness and genuine desire to insert knives in backs that characterize the intellectual at his deadliest. Massari had heard that Landino would lecture on Cicero's Epistolae ad Familiares during the academic year 1465-6. “I am an eager student,” he wrote to Guidetti on 14 September, “and I would be grateful to know what Landino said when he explained the first letter. For in my view it is quite hard because of the historical questions involved, and few have the ability to tackle so great an enterprise.“
