Nessun maggior dolore che ricordarsi del tempo felice nella miseria... - Dante Alighieri

The bitterest of woes Is to remember in the midst of pain A happy past;

your soul is sunken in that cowardice that bears down many men, turning their course and resolution by imagined perils, as his own shadow turns the frightened horse.

O you, who in some pretty boat,
Eager to listen, have been following
Behind my ship, that singing sails along

Turn back to look again upon your own shores;
Tempt not the deep, lest unawares,
In losing me, you yourselves might be lost.

The sea I sail has never yet been passed;
Minerva breathes, and pilots me Apollo,
And Muses nine point out to me the Bears.

You other few who have neck uplifted
Betimes to the bread of angels upon Which one lives and does not grow sated,

Well may you launch your vessel
Upon the deep sea.
