In Count Gismond,

They, too, so beauteous! Each a queen
By virtue of her brow and breast.

And the wonderful description of Pompilia by Caponsacchi:

Her brow had not the right line, leaned too much,
Painters would say; they like the straight-up Greek:
This seemed bent somewhat with an invisible crown
Of martyr and saint, not such as art approves.

In Eurydice,

But give them me, the mouth, the eyes, the brow!

In Count Gismond,

Our elder boy has got the clear
Great brow.

In The Statue and the Bust,

On his steady brow and quiet mouth.
