“The traditional picture of the blind old singer of Chios is largely made up of memories that go back to the time when a poet was a vates— a priestly and God-inspired seer. His blindness is merely the outward sign of the inward light that fills his being and enables him to see things others cannot see. This bodily infirmity expresses— as does the lameness of the divine smith Hephaestus—a second idea that was current in primitive times, that a maker of poems, ornaments and other products of handicraft can only come from the ranks of those who are unfit for war and foray. But apart from this feature, the legendary ‘Homer’ is an almost perfect example of the mythical poet who was still half-divine, a wonder-worker and a prophet. We find the clearest embodiment of this idea in Orpheus, the primeval singer who had his harp from Apollo and instruction in the art of song from the Muse herself; with his music he could move not merely men and beasts but even rocks and could reclaim Eurydice from the bonds of death.”
