Demodocus does not read out his poetry from a script; his inability to do so is underlined by the fact that he is blind (not incidentally, no one in the entire Odyssey reads or writes anything). Moreover, Demodocus does not invent an original story of his own composition. Instead, Demodocus is inspired by the Muse to sing the “deeds of heroes”—which are, at least in outline, already well-known to his audience.
