The White Elephant of Rucheni
The Desceliers map of 1550
"On a Renaissance map of the world known as Desceliers' World Map, 1550 , there is a small white elephant standing near the Arctic coast of Russia. How it got there is a mystery. Is it a mammoth, or does it symbolize something else? The solution is like a jigsaw puzzle. We have many pieces of evidence, in different colors and shapes. But it’s not clear that all of the pieces belong to the same puzzle and, in any case, too few pieces have survived for us to be able to construct a clear image of the thinking that led the artist to place that elephant in the frozen north. Perhaps the most important clue that we have to work with is that the elephant occupies a position that mapmakers had previously reserved for a monster that we now call the walrus."
