What the king does not know, however, is that the usurpation he fears has in effect already taken place: Achilles controls the army’s fate and will continue to do so, present or absent, as Achilles controls the epic. In the rebellion of Achilles, two powerful thematic lines have converged, one historical, one mythic: the historical reassessment of an individual’s unquestioned duty to his ruler and the playing out of Achilles’ inherently subversive destiny.
Caroline Alexander, The War That Killed Achilles , p. 36-37
Now the Sirens have a still more fatal weapon than their song, namely their silence. And though admittedly such a thing never happened, it is still conceivable that someone might possibly have escaped from their singing; but from their silence certainly never.
Franz Kafka, The Silence of the Sirens, 1917.
