Petrarch
Sonnet CC
HE PRAYS LOVE, WHO IS THE CAUSE OF HIS OFFENCES, TO OBTAIN PARDON FOR HIM

O Love, I err, and I mine error own,
As one who burns, whose fire within him lies
And aggravates his grief, while reason dies,
With its own martyrdom almost o'erthrown.
I strove mine ardent longing to restrain,
Her fair calm face that I might ne'er disturb:
I can no more; falls from my hand the curb,
And my despairing soul is bold again;
Wherefore if higher than her wont she aim,
The act is thine, who firest and spur'st her so,
No way too rough or steep for her to go:
But the rare heavenly gifts are most to blame
Shrined in herself: let her at least feel this,
Lest of my faults her pardon I should miss.

Macgregor.
