This is Henry Holiday's back cover illustration to Lewis Carroll's The Hunting of the Snark (1876).

Originally, the illustration was in black and white.

Huge (and perhaps not manageable for slow computers with small memory):
8000 × 12966

From a comment (1876) by Henry Holiday which he wrote on a letter from Lewis Carroll (Source: Sothebys):
"L.C. has forgotten that ‘the Snark’ is a tragedy…"


The Hunting of the Snark is not a nonsense poem, it's a tragedy. I think that this tragedy is about what happens when the search of truth turns into fanaticism.
