Leonardo DaVinci wrote in RTL

Leonardo wrote in Italian using a special kind of shorthand that he invented himself. People who study his notebooks have long been puzzled by something else, however. He usually used "mirror writing", starting at the right side of the page and moving to the left. Only when he was writing something intended for other people did he write in the normal direction.

People who were contemporaries of Leonardo left records that they saw him write and paint left handed. He also made sketches showing his own left hand at work. Being a lefty was highly unusual in Leonardo's time. Because people were superstitious, children who naturally started using their left hands to write and draw were forced to use their right hands.
