The book 'I Anatoliki Mesogeios Os Europaiki Istoria' (Tomos 1) may be regarded as his most important work.
The quintessence of his scientific and political work was to advert to the special importance of the Mediterranean as a bridge between Europe and the Middle East by means of his publications.
