In 1462, a monk arrived in Florence carrying a manuscript. It had been acquired in Macedonia by agents of Cosimo de Medici — the wealthiest man in Europe and an obsessive collector of ancient texts. Cosimo was in his seventies, dying, and he had been waiting a long time for something like this. He instructed his court philosopher, Marsilio Ficino, to set aside his translation of Plato’s complete works and begin on this manuscript immediately.
