It's going a bit further in time. but Alexander Pushkin is considered the father of Russian literature.

Michael Choniates is also a pretty famous byzantine writer/philosopher.

I think he's talking in terms of theologians from Byzantium glory days desu

Orthodoxy shuns innovators so most of their theologians were just hair-splitting pedants arguing over semantics. They rejected the scholastic tendency to meld philosophy with religion, so once they came up with a consistent Christology there was no need to add more to it.

Demetrios Kydones

He turned Catholic though

So we are talking just Byzantine theologians here?

I think the direct "opponent" of Saint Thomas Aquinas would be Gregory Palamas, not only in importance but due to their diametrically opposed ways, Aquinas, more rational, Palamas, more mystical:

This guy is somewhat famous in the west due to his book on demonology. He had a more hellenizing and Platonic view of Christianity:

This other is also somewhat notable and even more of a Platonist, bordering heresy:

Now this guy went full pagan, advocating a return to Greek polytheism and a refunding of the Byzantine Empire according to the principles laid out by Plato in the Republic. He met Cosimo de Medici at the Council of Florence, and convinced him to found a new Platonic Academy with Marsilio Ficino as the boss. He was thus an indirect influence in the development of the Italian Renaissance.
