Apollonius of Rhodes 
Jason and the Golden Fleece [EPUB ebook] 

A hero will have his day …It is a task that no man has ever completed: to bring back a magical ram’s fleece that lies hidden in a far-off land, guarded by an all-seeing serpent. But one man, Jason, must try. His life depends on it. Upon the orders of the King, Jason must cross deadly seas with the crew of his ship, the Argo, negotiate treacherous clashing rocks, fight fire-breathing bulls and confront the terror of the harpies before claiming his prize – and winning the heart of the witch-princess Medea.
