God's finger touched him, and he slept.

Let me go: take back thy gift:
Why should a man desire in any way
To vary from the kindly race of men,
Or pass beyond the goal of ordinance
Where all should pause, as is most meet for all?
...Why wilt thou ever scare me with thy tears,
And make me tremble lest a saying learnt,
In days far-off, on that dark earth, be true?
‘The Gods themselves cannot recall their gifts.’
- Tithonus

But thy strong Hours indignant work’d their wills,
And beat me down and marr’d and wasted me,
And tho’ they could not end me, left me maim’d
To dwell in presence of immortal youth,
Immortal age beside immortal youth,
And all I was, in ashes.
- Tithonus

'Tis very certain the desire of life prolongs it.

Sweet is true love that is given in vain, and sweet is death that takes away pain.

Boldly they rode and well,
Into the jaws of Death,
Into the mouth of hell.
