Holiday and Gheeraerts I

Illustrations by Henry Holiday (from The Hunting of the Snark,1876) and Marcus Gheeraerts the Elder (Allegory of Iconoclasts around 1567): In the "mouth" of Gheeraert's "head" a praying priest is depicted. The shape of the priest also is visible in the "mouth" of Holiday's vanishing "Baker".

This is not plagiarism. This is a puzzle in a picture similar to puzzles in textual artwork (poetry,novels etc.), where readers are challenged to detect references to other writers. Holiday may have used the shape of the priest in his own illustration in order to indicate to the beholder a relation to Gheeraert's illustration. Holiday also used other elements from Gheeraert's etching in his own work.
