Ulises (extracto)

Come my friends
'Tis not too late to seek a newer world
for my purpose holds to sail beyond the sunset.

And though we are not now that strength
which in old days moved earth and heaven;
that which we are, we are;
one equal temper of heroic hearts,
made weak by time and fate, but strong in will,
to strive, to seek, to find, and not to yield.

Alfred Lord Tennyson
