The advantage of Browning is that he has used the sensuous imagery for ethical symbolism; here he greatly surpasses Jonson, though it would be hard to improve upon the beauty of Jonson's verses, as merely describing visual beauty.

Here are Jonson's stanzas: THE TRIUMPH See the Chariot at hand here of Love, Wherein my Lady rideth! Each that draws is a swan or a dove, And well the car Love guideth.
As she goes, all hearts do duty Unto her beauty; And enamoured do wish, so they might But enjoy such a sight, That they still were to run by her side, Through swords, through seas, whither she would ride.
Do but look on her eyes, they do light All that Love's world compriseth! Do but look on her hair, it is bright As love's star when it riseth! Do but mark, her forehead's smoother Than words that soothe her; And from her arch'd brows such a grace Sheds itself through the face, As alone there triumphs to the life All the gain, all the good, of the elements' strife.
Have you seen but a bright lily grow Before rude hands have touched it?
Have you mark'd but the fall of the snow Before the soil hath smutch'd it?
Have you felt the wool of beaver Or swan's down ever?
Or have smelt o' the bud o' the brier, Or the nard in the fire?
Or have tasted the bag of the bee?
O so white, O so soft, O so sweet is she! The first of the above stanzas is a study after the Roman poets; but the last stanza is Jonson's own and is very famous.

You will see that Browning was probably inspired by him, but I think that his verses are much more beautiful in thought and feeling.
There is one type of ideal woman very seldom described in poetry--the old maid, the woman whom sorrow or misfortune prevents from fulfilling her natural destiny.

Commonly the woman who never marries is said to become cross, bad tempered, unpleasant in character.

She could not be blamed for this, I think; but there are old maids who always remain as unselfish and frank and kind as a girl, and who keep the charm of girlhood even when their hair is white.
