"The Formation of the Hellenic Christian Mind" par Demetrios Constantelos, (ISBN0-89241-588-6) [1]: "The fifth century marked a definite turning point in Byzantine higher education. Theodosios ΙΙ founded in 425 a major university with 31 chairs for law, philosophy, medicine, arithmetic, geometry, astronomy, music, rhetoric and other subjects. Fifteen chairs were assigned to Latin and 16 to Greek. The university was reorganized by Michael ΙII (842–867) and flourished down to the fourteenth century".
