Petrarch's Canzoniere (Rime Sparse) 102 - Verse Translation
This is my new verse translation; for a more literal translation have a look at this one.
Caesar, when the Egyptian traitor
Gifted him that honoured head,
Hid his joy and, as is written,
Wept crocodile tears, instead;

And Hannibal, who saw his empire
Torn by vicious fortune's whim
Laughed amongst his tearful people
And kept his bitterness within;

And my soul too wears this strange cloth
That's sometimes clear, and lets you see my mood
And sometimes not;

So should I ever laugh or sing
It is because these are the only things
That hide my weeping.
