 Another narrative on the constellations , three paragraphs long , is from a Latin writer whose brief notes have come down to us under the name of Hyginus . It begins with the oxhide story of Orion 's birth , which this source ascribes to Callimachus and Aristomachus , and sets the location at Thebes or Chios . Hyginus has two versions . In one of them he omits Poseidon ; a modern critic suggests this is the original version .
