“Yet I admire Phemius, who helped me to smooth out incidents in which the Goddess Athene had not been particularly helpful. For safety’s sake, on his advice, I have consigned to oblivion all the names of my living characters, giving them pseudonyms—as I also do here, with only four exceptions. I retain my own as a personal signature; Phemius retains his as a reward for the collaboration; I allow Odysseus to call himself “Aethon son of Castor” and tell Aethon’s life story in one of his many fictions; and (as I decided halfway through the poem) Eurycleia deserves to be immortalized for urging Aethon and me to marry.”
