Gemistus Pletho

Georgios Gemistos Plethon (Greek: Γεώργιος Γεμιστὸς Πλήθων; Latin: Georgius Gemistus Pletho c. 1355/1360 – 1452/1454), commonly known as Gemistos Plethon, was a Greek scholar and one of the most renowned philosophers of the Late Byzantine era. He was a chief pioneer of the revival of Greek scholarship in Western Europe. As revealed in his last literary work, the Nomoi or Book of Laws, which he circulated only among close friends, he rejected Christianity in favour of a return to the worship of the classical Hellenic gods, mixed with ancient wisdom based on Zoroaster and the Magi.

In 1438–1439, he reintroduced Plato's ideas to Western Europe during the Council of Florence in a failed attempt to reconcile the East–West Schism. Plethon also formulated his political vision in several speeches throughout his life. The boast in one of the speeches that "We are Hellenes by race and culture" and his proposal of a reborn Byzantine Empire following a utopian Hellenic system of government centered in Mystras, have generated discussion about Byzantine and modern Greek identity. In this regard, Plethon has been labelled both "the last Hellene" and "the first modern Greek".
