“Song, if you find a man at peace with love,
say: 'Die while you're happy,
since early death is no grief, but a refuge:
and he who can die well, should not delay.”
Canzon, s'uom trovi in suo amor viver queto,
di': Muor' mentre se' lieto,
ché morte al tempo è non duol, ma refugio;
et chi ben pò morir, non cerchi indugio.
Canzone 331, st. 6 ( tr. A. S. Kline http://petrarch.petersadlon.com/canzoniere.html?poem=331)

If I should die, reported in Bartlett's Familiar Quotations, 10th ed. (1919). Compare: "If I should die to-night, / My friends would look upon my quiet face / Before they laid it in its resting-place, / And deem that death had left it almost fair", Belle E. Smith.
