By Gabriel-c.1869-Eden Bower.”
The sketch illustrates a key element of DGR's poem Eden Bower
As part of a double work of art, the picture is uncommon because it was made for the poem; normally DGR wrote his poems to illustrate his pictures.
The drawing may have been executed at the time DGR wrote the poem; but it might just as well belong to 1863-1864, when (according to Robert Browning) DGR executed a picture on this subject. Whether he had any thought to elaborate the sketch further is unknown.
The drawing was made as a pictorial companion to DGR's poem
