But if the day ever comes when Vulcan succeeds, I do not think I will accept the gift. Not unless Danni receives her own immortality at the same time.
Certain gods remind me, from time to time, that I am still only mortal—as if the fact gave them cause for worry. It does not much concern me. I have already faced Thanatos once, and in my heart I still believe what I suppose I have always believed, that some inner essence of humanity is naturally immune to death. So, I am no more and no less immortal than Danni at my side, or any of those who envy me my strength—or than any of you who read my words.
Besides, even gods must die, as was thoroughly demonstrated in our war with the Giants. And if Vulcan is ever able to grant me such a gift, and I accept it, then when I die the Face of Hercules must pass to someone else.
Here I conclude this story of my life. But my life is not yet over. Danni will bear me sons and daughters, and I do not think any god will be so foolish as to try to serve me as Zeus once served Amphitryon.
