Petrarchan sonnet
In what bright realm, what sphere of radiant thought. A
Did Nature find the model whence she drew. B
That delicate dazzling image where we view. B
Here on this earth what she in heaven wrought? A
What fountain-haunting nymph, what dryad, sought. A
In groves, such golden tresses ever threw. B
Upon the gust? What heart such virtues knew?—. B
Though her chief virtue with my death is frought. A
He looks in vain for heavenly beauty, he. C
Who never looked upon her perfect eyes, D
The vivid blue orbs turning brilliantly –. C
He does not know how Love yields and denies; D
He only knows, who knows how sweetly she. C
Can talk and laugh, the sweetness of her sighs. D
