This is exactly the sentiment of Petrarch:

Pur mi consola, che morir per lei
Meglio è che gioir d'altra—

But it is one of those thoughts which spring in the heart, and might often be repeated without once being borrowed.

Thibault fût Roi galant et valoureux,
Ses hâuts faits et son rang n'ont rien fait pour sa gloire;
Mais il fût chansonnier—et ses couplets heureux,
Nous ont conservé sa mémoire.

If lusty Love should go in quest of beauty,
Where should he find it fairer than in Blanche?
If zealous Love should go in search of virtue,
Where should he find it purer than in Blanche?
If Love, ambitious, sought a match of birth,
Whose veins bound richer blood than Lady Blanche?
