Cited from the book:

“Swiss nationalism is, as we know, pluri-ethnic. For that matter, if we were to suppose that the Greek mountaineers who rose against the Turks in Byron’s day were nationalists, which is admittedly improbable, we cannot fail to note that some of their most foremidable fighters were not Hellenes but Albanians (the Suliotes)”
