And Nisus says: “Euryalus, is it
the gods who put this fire in our minds,
or is it that each man’s relentless longing
becomes a god to him? Long has my heart
been keen for battle or some mighty act;
it cannot be content with peace or rest.
(Aeneid IX 243-247, tr. Mandelbaum)
Strikingly modern, that.
