Means "manifestation of God" from Greek
θεος (theos) "god" and
φανης (phanes) "appearing". This name was borne by a few saints, including an 8th-century chronicler from Constantinople and a 19th-century Russian Orthodox saint, Theophanes the Recluse, who is
Феофан (Feofan) in Russian. Another famous bearer was a 14th-century Byzantine icon painter active in Moscow.
