No way to parry this strong stroke of fate?

None save my own self-when these bonds are loosed.

And who shall loose them if Zeus wills not?

The thirteenth generation shall beget.

Then seek not thou to know thine own fate.

Tender me not a boon to snatch it from me.

Of two gifts thou hast asked one shall be thine.

What gifts? Pronounce and leave to me the choice.
