Leonardo’s Notebooks
Leonardo wrote in his notebooks backwards, from right to left, so that they had to be held up to a mirror to be read.
In a manner of speaking, the image of Leonardo’s notebooks would be more real than the notebooks themselves.
Leonardo was also left-handed. And a vegetarian. And illegitimate.
-David Markson, Wittgenstein’s Mistress
