The Latin says
Chaldean oracles with scholia of Psellus and Phethon. "Βίῃ λιπόντων σῶμα ψυχαὶ καθαρώταται." "By the force of the body, they abandon the purest soul."
The Greek is some Chaldean oracle text, and "scholia" is explanatory comments (something I'm doing right now!).
Chaldean Oracles - Wikipedia
The Chaldean Oracles are a set of spiritual and philosophical texts widely used by Neoplatonist philosophers from the 3rd to the 6th century CE. While the original texts have been lost, they have survived in the form of fragments consisting mainly of quotes and commentary by Neoplatonist writers.
No idea who is "Phethonis".
Psellus was a Byzantine Greek monk, savant, writer, philosopher, politician, historian and music theorist. He was born in 1017 or 1018, and is believed to have died in 1078.
He was a major fan of mystical Neo-Platonism, which is something Thomas Browne was also into.
Psellos was universally educated and had a reputation for being one of the most learned men of his time. He prided himself on having single-handedly reintroduced to Byzantine scholarship a serious study of ancient philosophy, especially of Plato. His predilection for Plato and other pagan (often Neoplatonic) philosophers led to doubts about the orthodoxy of his faith among some of his contemporaries, and at one point he was forced to make a public profession of faith in his defense.
In his Hellenism in Byzantium, Anthony Kaldellis states the following of Michael Psellos:
He expresses contradictory opinions regarding the worth of the Chaldean Oracles and goes on at length about topics that he then suddenly dismisses as nonsense, which has been seen as a possibly 'hypocritical compliance with the tenets of Christianity.'
