Anna Komnene
Accounts from the 11th century onward (from Anna Komnene, Michael Psellos, John III Vatatzes, George Gemistos Plethon and several others) prove that the revival of the term Hellene (as a potential replacement for ethnic terms like Graikos and Romaios) did occur. For example, Anna Komnene writes of her contemporaries as Hellenes, but does not use the word as a synonym for a pagan worshiper. Moreover, Anna boasts about her Hellenic classical education, and she speaks as a native Greek and not as an outsider/foreigner who learned Greek.
