How sweet and lovely dost thou make the shame
Which, like a canker in the fragrant rose,
Doth spot the beauty of thy budding name!
O! in what sweets dost thou thy sins enclose.
That tongue that tells the story of thy days,
Making lascivious comments on thy sport,
Cannot dispraise, but in a kind of praise;
Naming thy name blesses an ill report.
O! what a mansion have those vices got
Which for their habitation chose out thee,
Where beauty's veil doth cover every blot
This line explains the logic behind the three preceding lines. Nothing bad can be said about the young man, because his name alone makes anything that is said about him a compliment. This convoluted reasoning is reminiscent of the sort of comment that might appear in a seduction poem.
