Gemistus Pletho
Georgius Gemistus Pletho (; /1360 – 1452/1454) was 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 only circulated 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".
