Theophanes Nonnus

Theophanes Nonnus (or Nonnos)—or Theophanes Chrysobalantes/Chrysobalantites Θεοφάνης Χρυσοβαλάντης or Χρυσοβαλαντίτης (see below)—(c. 950) was a Byzantine physician who wrote an outline of medicine dedicated to Emperor Constantine VII Porphyrogenitus.

Identity
The extant manuscripts identify the author as Theophanes; the name 'Nonnus' was apparently fabricated by the copyist Andreas Darmarios. The name Chrysobalantes was either an epithet or a variant of the documented Byzantine family name Chrysobalantites. (Sonderkamp, 1984)
