Now this is my kind of map:
From Strange Maps, a favorite site of mine for many reasons, this fine chart posted today belongs to the Bellman in Lewis Carroll’s “The Hunting of the Snark”.
It helps the Bellman and his fellow adventurers, who are hunting for a legendary beast called the Snark, to cross the ocean and arrive at a strange land. The absurdity of the map is that it only shows ocean, literally illustrating nothing, and therefore cannot be a very helpful navigating tool.
Ah, but it tells you precisely where you are. :)
