Goblet Again

And passing by Arabia he slew Emathion, son of Tithonus, and journeying through Libya to the outer sea he received the goblet from the Sun. And having crossed to the opposite mainland he shot on the Caucasus the eagle, offspring of Echidna and Typhon, that was devouring the liver of Prometheus, and he released Prometheus, after choosing for himself the bond of olive, and to Zeus he presented Chiron, who, though immortal, consented to die in his stead.
