Homer was a blind bard

Homer may not even have existed, let alone been blind. And if he did exist, may not have written both the Iliad and the Odyssey. And if he did write them, very well may not have written them from scratch (but was instead just the person responsible for writing down what became the definitive version of a more widespread oral tradition). So he's perhaps not the best example to use. (The notion that he's blind is based on the assumption that a certain bardic character in his writing was a self-insert.)
