Leonardo purposefully left parts of his designs off his notebooks to prevent plagiarism. He also wrote notes and directions backwards so that the reader had to hold a mirror to his writing to read what was written. While some believe that this was another way to prevent plagiarism, others suggest that he wrote this way because he was left handed and didn't want the ink to smear as he moved his hand across the paper.
