Alfred Parsons' depiction of Charles Darwin's study in Downe. The wood cutter was J. Tynan.

I assume that Alfred Parsons quoted shapes from Henry Holiday's illustration (cut by Joseph Swain) to The Bakers Tale in Lewis Carroll's The Hunting of the Snark in a similar manner as Henry Holiday used shapes in the works of earlier artists perhaps in order to "point" to these works. The match of each single shape could be quite incidental, but the the spacial relation of most shapes to each other also matches well. That is less likely to be just incidental.

This is one of the images which I posted on Flickr a few years ago. It is an earlier version of the image below:
