Always something interesting and entertaining at the Elephant’s place. I have no idea who Orson is or the Green Knight but the illustrator, Walter Crane, lived from 1845 to 1915 and helped in defining the “child nursery motif” of the late 19th Century. He was also a socialist, bordering on anarchism and believed that art should be part of the daily life of all people. (http://en.wikipedia.org/wiki/Walter_Crane)
But Orson threw the Green Knight down, and bound him with a chain,
And set the lady free; both brothers then start off to gain
The Green Knight’s castle-gates – two roaring lions keep guard there,
But down they crouched when they beheld the brothers void of fear.
From the story “Valentine And Orson”
