Leonardo was naturally left-handed and  wrote notebook entries in mirror (backwards) script, a trick that requires a mirror to be read and  which help to keep many of his observations from being widely known.
Leonardo worked for Ludovico Sforza, Duke of Milan, for nearly eighteen years (1482-99).  Leonardo was a vegan.
He is best known for his paintings “The Last Supper” and especially the “Mona Lisa” (La Giocondane). Leonardo apparently was quite fond of the completed work, as it accompanied him on all of his travels.
Sigmund Freud said: “Leonardo da Vinci was like a man who awoke too early in the darkness, while the others were all still asleep”.
