J. B. Bury Quote

Not long after his (Justinian) accession, he reaffirmed the penalties which previous Emperors had enacted against the pagans, and forbade all donations or legacies for the purpose of maintaining "Hellenic impiety,"... by making the profession of (Christian) orthodoxy a necessary condition for public teaching Justinian accelerated the extinction of "Hellenism."... This event had a curious sequel. Some of the philosophers whose occupation was gone resolved to cast the dust of the Christian Empire from their feet and migrate.
