Author of the first known literature of Europe, he had a lasting effect on the Western canon. The importance of Homer to the ancient Greeks is described in Plato's "Republic", which portrays him as the protos didaskalos, "first teacher", of the tragedians, the hegemon paideias, "leader of Greek culture", and the ten Hellada pepaideukon, "teacher of [all] Greece". Fragments of Homer account for nearly half of all identifiable Greek literary papyrus finds in Egypt.
