The most important event of Gemistos's life was the journey which he took to Italy in the train of John Palæologus in 1438. Secretly disliking Christianity in general, and the Latin form of it in particular, he had endeavoured to dissuade the emperor from attending the Council. Now he found himself elected as one of the six champions of the cause of the Greek Church. For the subtle Greek intellect in that dotage of a doomed civilisation, no greater interest survived than could be found in dialectic; and to dispute about the _filioque_ of the Christian creed was fair sport, when no chance offered itself of forcing rationalistic Paganism down the throat of popes and cardinals. Therefore it is probable that Gemistos did not find his position at the Council peculiarly irksome, even though he had to listen to reasonings about purgatory and the procession of the Holy Ghost, and to suggest arguments in favour of the Eastern dogma, while in his inmost soul he equally despised the combatants on either side.
The effect he produced outside the Council was far more flattering than the part he had to play within the walls of Santa Maria Novella. Instead of power-loving ecclesiastics and pig-headed theologians, anxious only to extend their privileges and establish their supremacy, he found a multitude of sympathetic and enthusiastic listeners. The Florentines were just then in the first flush of their passion for Greek study. Plato, worshipped as an unknown god, whose rising would dispel the mists of scholastic theology, was upon the lips of every student. Men were thirsting for the philosophy that had the charm of poetry, that delighted the imagination while it fortified the understanding, and that lent its glamour to the dreams and yearnings of a youthful age. What they wanted, Gemistos possessed in abundance. From the treasures of a memory stored with Platonic, Pythagorean, and Alexandrian mysticism he poured forth copious streams of indiscriminate erudition. The ears of his audience were open; their intellects were far from critical. They accepted the gold and dross of his discourse alike as purest metal. Hanging upon the lips of the eloquent, grave, beautiful old man, who knew so much that they desired to learn, they called him Socrates and Plato in their ecstasy. It was during this visit to Florence that he adopted the name of Plethon, which, while it played upon Gemistos, had in it the ring of his great master's surname.[180] The devotion of his Greek disciples bore no comparison with the popularity he acquired among Italians; and he had the satisfaction of being sure that the seed of Platonic philosophy sown by him would spring up in the rich soil of those powerful and eager minds. Cosimo de' Medici, convinced of the importance of Platonic studies by his conversations with Gemistos, founded the famous Florentine Academy, and designated the young Marsilio Ficino for the special task of translating and explaining the Platonic writings.[181] When we call to mind the influence which the Platonic Academy of Florence, through Ficino and Pico della Mirandola, exerted over the whole thought of Italy, and, through Reuchlin and his pupil Melanchthon, over that of Germany, we are able to estimate the impulse given by Gemistos to the movement of the fifteenth century. It may be added that Platonic studies in Italy never recovered from the impress of Neoplatonic mysticism which proceeded from his mind.
