Blind Faith

Homer is considered the author of two of the greatest cycles of myths ever produced, The Illiad and The Odyssey. He lived (if indeed he was an individual) around the dawn of recorded history. He is represented as blind because his sight is inward - to the wisdom within and above.
These myths can be seen as full of symbolism that is extraordinarily subtle. An exploration, in process, of The Odyssey can be found here.
The word 'myth' has a root meaning that may come from the word 'murmuring'. There is a sense in which the myth murmurs a truth that goes way beyond historical facts. Being full of symbols that can far transcend the material realm, the myth, carefully considered, can help the consciousness to ascend far above the everyday and mundane.
The Greeks recognised this and considered their mythic dramas to have a cathartic quality, that in some sense cleansed the Soul.
