Message to the Public Domain Review: You are using my comparison (from December 2008) without proper referencing. This was my first discovery of one of Henry Holiday’s allusions. This finding started my Snark hunt. I think that Public Domain Review should specify the source (my proposal).
From https://publicdomainreview.org/collection/the-art-of-hidden-faces-anthropomorphic-landscapes#17-0 (Snapshot 2019-10-10):
Marcus Gheeraerts the Elder’s allegory of iconoclasm, ca.1566 — Source.
The next picture is an illustration by Henry Holiday for Lewis Carroll’s The Hunting of the Snark. The face hidden in the darkness of the trees is thought to be based on Geheert’s iconoclasm image above.
The tenth of Henry Holiday’s original illustrations to Lewis Carroll’s The Hunting of the Snark, 1876 — Source.
By the way, it’s not “the 10th” of Henry Holiday’s original illustrations to Lewis Carroll’s The Hunting of the Snark. Holiday contributed only nine (not ten) illustrations to The Hunting of the Snark and two illustrations for the book cover. The Ocean Chart probably had been made by a typesetter, not by Henry Holiday.
And there are various way’s to write Gheeraert’s name. 😉
