Your most beautiful bit, that hath all eyes upon her,

That her honesty sells for a hogo of honour ;

Whose lightness and brightness do shine in such splendor,

That none but the stars are thought fit to attend her :

Though now she be pleasant and sweet to the sense,

Will be damnably mouldy a hundred years hence. 

[Thomas Jordan, 17c.]
