George Gemistos Plethon was a Byzantine philosopher and scholar born around 1355. He is best known for his revival of ancient Greek philosophy, particularly the works of Plato. Plethon played a significant role in the Renaissance, influencing the intellectual landscape of Western Europe through his teachings and writings. Plethon's most notable work is the "Nomoi" (Laws), which presents his philosophical ideas and vision for a new society. He was also instrumental in the establishment of the Platonic Academy in Florence, where he shared his ideas with prominent thinkers of the time, contributing to the broader movement of humanism.
