After graduating from the Greek school of Skoutarion, he worked for a living. He became a shareholder in the commercial business of Chrysvergi.[1] At the same time he learned other languages, Turkish, Russian, Bulgarian and French.[2] He was involved in historical researches very early and published them in the magazine of the Hellenic Philological Association, which belonged to the Archaeological Commission of which he became a chairman.
