All old stories, my cousin, will bear telling and telling again in different ways. What is required is to keep alive, to polish, the simple clean forms of the tale which be there - in this case the angry Ocean, the terrible leap of the horse, the fall of Dahud from the crupper, the engulfment etc etc. And yet to add something of yours, of the writer, which makes all these things seem new and first seen, without having been appropriated for private or personal ends.
