Siniossoglou, Niketas. Radical Platonism in Byzantium. Cambridge University Press, 2011. ISBN 9781107013032. с. 50 – 51. It is worth evoking here the pioneering theory of Konstantinos Sathas regarding the survival of pagan Hellenism within Byzantium. Sathas did not maintain that paganism ultimately shaped the Christian mysteries from inside, as Protestant and deist philosophers had done. Rather, Sathas, nowadays considered eccentric and very rarely (if at all) remembered by modern Byzantinists, argued in favour of a covert pagan movement operating within the Christian Empire and bowing to clerical hegemony while maintaining its own distinct identity.
