Leonardo da Vinci

Creator of the world-famous painting the Mona Lisa, Leonardo da Vinci is widely considered the greatest genius of all time, his knowledge and ingenuity extending far beyond the field of art. A scientist and inventor, he experimented with flight, studied the human anatomy, and conducted military expeditions. However, some details of his life are less well known. As an artist, he completed only a few works of art, including The Last Supper, and many of his inventions never came to fruition. In his personal writing, he oftem employed "mirror writing," writing in reverse from right to left. He traveled extensively and died in France more than 500 years ago, leaving many mysteries about his life behind. Source: Shogakukan
