When people think of DaVinci, they tend of think of the Mona Lisa or the Vitruvian Man or The Last Supper, but he was such a prolific artists with so many great works. What is your favorite creation by DaVinci? 
I love the creation of the last dinner, everytime i see it , it makes me cry.
There is a theory that DaVinci hid musical notes in that painting. A musician named Giovani Maria Pala composed a short melody that was supposedly drawn from the music in the painting. 
Maybe its tru but i heard another curiosity that if you decode Davincis paintings you can learn about our history and where we came from. They are just gossips 
What do you think it is about DaVinci that inspires so many theories about his work? 
He gives his soul in the paintings and nobody can paint like him, im sure he says more that we see in his paintings.
It's remarkable to think about the fact that he never really studied or trained as an artist. 
He was born to paint, he must be a 1 in a billion person with high HQ 
For someone living in 1500 to come up with ideas for parachutes and diving gear, he certainly must have been a genius. 
Yes , among the most genius person of that time and of the present time.
