How did Leonardo da Vinci disguise his handwriting?
by using invisible ink
by mirror writing
by using Ceasar's code
by using classical Greek
Leonardo's writings are mostly in mirror-image cursive. The reason may have been more a practical expediency than for reasons of secrecy as is often suggested. Since Leonardo wrote with his left hand, it is probable that it was easier for him to write from right to left.
