My first Snark encounter was in 2005. Then, after almost four years, 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.
The image shows 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.
And there are more big heads.

In his illustrations to Lewis Carroll's "The Hunting of the Snark" (1876), Henry Holiday might have referred to a detail in this panel of the Isenheim Altarpiece. pic.twitter.com/Q0AruMIpps

Blurring images is low pass filtering images. An artist’s blunted sight can have the same effects like blurring with computerized image processing. Sometimes you need to get rid of distracting details in order to get the whole picture.
‘s what Salvador Dalí taught me about creative work
will help you to (perhaps) get the whole picture. However, keep in mind that artists like to play with what the beholders of their work might want (or might not want) to percieve. Even without blurring, artists can deny anything you “see” in an ambiguous creation: They play with their own pareidolia as well as with the pareidolia of their audience.
Before computerized image processing was available, artists use simple techniques to blur images. For example, looking at an image through a feather did the trick.
Blurring might help you to see things which you wouldn’t see with clear sight. It’s fine to try that with artwork which might have been intentionally created for such an exercise. But better make sure that it was an artist who created the face that is looking at you. I don’t know whether Mars ever has been inhabited by artists.
Rather than suffering from pareidolia, artists get inspired by it.
Sometimes blurring helps to reveal structures hidden in the hatching.

Artists, who have played with their own pareidolia first, know how to play with the pareidolia of the beholders of their works.
I incidentally found this in December 2017 as bycatch from my Snark hunt:
