I entered the Snark hunting grounds in December 2008. http://www.artandpopularculture.com/User:Goetzkluge could give you an idea where I was in 2010.
Illustrations by Henry Holiday (from The Hunting of the Snark, 1876) and Marcus Gheeraerts the Elder (Allegory of Iconoclasts, aka The Image Breakers, around 1567): In the “mouth” of Gheeraerts’ “head” a praying priest is depicted. The shape of the priest also is visible in the “mouth” of Holiday’s vanishing “Baker”.
There is more — with acknowledgments to Mahendra Singh, to John Tufail and to the Internet.

This blog is mostly about Lewis Carroll‘s, Henry Holiday‘s and Joseph Swain‘s illustrations to The Hunting of the Snark.
In his Illuminated Snark, John Tufail assumed that the night sky in the front cover of The Hunting of the Snark could be a map. Together with my assumption that Henry Holiday drew inspiration from several paintings by Marcus Gheeraerts the Younger, John’s paper helped me to find the Ditchley Portrait. That again helped me to find the painting by an anonymous artist depicting Elizabeth I at old age.

Usually elements borrowed by Henry Holiday from other artists are inconspicuously integrated into Holiday’s illustrations. Here is an exception. The monstrance-shaped tree is just a small element in John Martin’s The Bard. In Holiday’s illustration it is more prominent.
