Analysis of To Roses in the Bosom of Castara

YE blushing virgins happy are
   In the chaste nunnery of her breasts--
For he'd profane so chaste a fair,
   Whoe'er should call them Cupid's nests.

Transplanted thus how bright ye grow!
   How rich a perfume do ye yield!
In some close garden cowslips so
   Are sweeter than i' th' open field.

In those white cloisters live secure
   From the rude blasts of wanton breath!--
Each hour more innocent and pure,
   Till you shall wither into death.

Then that which living gave you room,
   Your glorious sepulchre shall be.
There wants no marble for a tomb
   Whose breast hath marble been to me.
