 Thus a certain diglossia between spoken Greek and written, classical Greek may be discerned.Major genres of Byzantine literature include historiography (both in the classical mode and in the form of chronicles), hagiography (in the form of the biographical account or "bios" and the panegyric or "enkomion"); hagiographic collections (the "menaia" and "synaxaria"), epistolography, rhetoric, and poetry.From the Byzantine administration, broadly construed, we have works such as description of peoples and cities, accounts of court ceremonies, and lists of precedence.
