"This shifted the centre of a truly Hellenic civilization to the east, to the Aegean, the Ionian littoral of Asia Minor and to Constantinople. It also meant that modem Greeks could hardly count as being of ancient Greek descent, even if this could never be ruled out.’ There is a sense in which the preceding discussion is both relevant to a sense of Greek identity, now and earlier, and irrelevant. It is relevant in so far as Greeks, now and earlier, felt that their ‘Greekness’ was a product of their descent from the ancient Greeks (or Byzantine Greeks), and that such filiations made them feel themselves to be members of one great ‘super-family’ of Greeks, shared sentiments of continuity and membership being essential to a lively sense of identity. It is irrelevant in that ethnies arc constituted, not by lines of physical descent, but by the sense of continuity, shared memory and collective destiny, i.e. by lines of cultural affinity embodied in distinctive myths, memories, symbols and values retained by a given cultural unit of population. In that sense much has been retained, and revived, from the extant heritage of ancient Greece. For, even at the time of Slavic migrations, in Ionia and especially in Constantinople, there was a growing emphasis on the Greek language, on Greek philosophy and literature, and on classical models of thought and scholarship. Such a ‘Greek revival’ was to surface again in the tenth and fourteenth centuries, as well as subsequently, providing a powerful impetus to the sense of cultural affinity with ancient Greece and its classical heritage."
