And they two girded themselves to slay the steers, proud Ancaeus and Heracles.

The latter with his club smote one steer mid-head on the brow, and falling in a heap on the spot, it sank to the ground; and Ancaeus struck the broad neck of the other with his axe of bronze, and shore through the mighty sinews; and it fell prone on both its horns.

Their comrades quickly severed the victims' throats, and flayed the hides: they sundered the joints and carved the flesh, then cut out the sacred thigh bones, and covering them all together closely with fat burnt them upon cloven wood.
And Aeson's son poured out pure libations, and Idmon rejoiced beholding the flame as it gleamed on every side from the sacrifice, and the smoke of it mounting up with good omen in dark spiral columns; and quickly he spake outright the will of Leto's son: "For you it is the will of heaven and destiny that ye shall return here with the fleece; but meanwhile both going and returning, countless trials await you.

But it is my lot, by the hateful decree of a god, to die somewhere afar off on the mainland of Asia.

Thus, though I learnt my fate from evil omens even before now, I have left my fatherland to embark on the ship, that so after my embarking fair fame may be left me in my house." Thus he spake; and the youths hearing the divine utterance rejoiced at their return, but grief seized them for the fate of Idmon.
