The photogravure triptych plate is used as an illustration for Chapter IX of "Sonnets of the Portuguese" by Elizabeth Barrett Browning. This photogravure from the second edition, 1920 (?) published by George G. Harrap & Co.
The poem begins:
Can it be right to give what I can give?
To let thee sit beneath the fall of tears
As salt as mine, and hear the
sighing years
Re-sighing on my lips renunci-
ative
Through those infrequent smiles which fail to live
For all thy adjurations? O my fears,
That this can scarce be right!
