Delia VI: Fair is my love, and cruel as she's fair

VI
Fair is my love, and cruel as she's fair:
Her brow shades frowns although her eyes are sunny,
Her smiles are lightning though her pride despair,
And her disdains are gall, her favours honey;
A modest maid, deck'd with a blush of honour,
Whose feet do tread green paths of youth and love,
The wonder of all eyes that look upon her:
Sacred on earth, design'd a saint above.
Chastity and beauty, which were deadly foes,
Live reconciled friends within her brow;
And had she pity to conjoin with those,
Then who had heard the plaints I utter now?
For had she not been fair and thus unkind,
My muse had slept, and none had known my mind.
