The image you see here, when combined with a few moments’ thought, provides the answer to the puzzling question: How can one write in a completely foreign language?
The solution to that puzzle is: On a piece of paper, handwrite any phrase you like, in a language you do know. Then rotate the paper 180 degrees. What you now see will appear to be — and who can say for sure that it’s not? — words written in a completely foreign language.
