If one chaste love, if one divine compassion,
If one destiny is equal for two lovers,
If one hard fate of the one is felt by the other,
If one spirit, if one will guides two hearts;
If one soul in two bodies makes itself eternal,
Lifting both to heaven with a single wing,
If Love in one blow and one golden arrow
The hearts in two chests can burn and tear;
If the one loves the other and neither loves himself,
With one pleasure and one delight, to such a measure
That one and the other desire to reach a single end:
Thousands and thousands would not make a hundredth
Of such a knot of love, or of such a faith:
And only anger could break and untie it.

Michelangelo Buonarroti
