Andrew Lang's The Crimson Fairy Book was originally published in 1903. My Dover reprint includes reproductions of the illustrations that appeared in that original publication--you know the sort, those crowded ink drawings of girls with overflowing hair and draperies twining around their ankles, those baby-faced boys with pointed shoes and come-hither skin, and those exquisitely toothed monsters. And everyone, even the monster who is getting strangled, appears to be swooning with desire.
In addition to being full of naked boys tied to horses, each of these illustrations has a caption, and those captions themselves are as a good as a tale. For instance:
The Faithful Servant turns to stone.
She lived happily in her Nest.
The Prince lets out the Hairy Man.
The Boy who could keep a Secret.
The Witch loses her Iron Nose.
The Bald headed Man on the Mountain.
This would be a fine writing prompt: to invent a new tale based only on an illustration and its caption. Maybe I should try it.
