In a well-formed paragraph, discuss the speaker, the context and the significance of the following quotation.  You do not need to repeat the quotation in your answer. “So now at last, you gods, you train your spite on me for keeping a mortal man beside me.  The man I saved, Riding astride his keel-board, all alone, when Zeus with one hurl of white-hot bolt had crushed his racing warship down the wine-dark sea.”           (Odyssey, Book 5, lines 143-147, page 156)
