"Saint John the Baptist" by Leonardo da Vinci
Let’s start with Duh Vinci’s last known painting. I think after a long and tedious career hiding codes and subliminal messages in paintings Leo threw in the towel and laid it all out for us in this picture. Who cares why the Mona Lisa is smiling? Why is John smiling? After all, he is about to be beheaded! As a painting from the Italian Renaissance Master it is so-so, but as a message to the world it is a very powerful piece. Duh Vinci is screaming, look up you idiots – that’s my home planet up there – I am an alien! Duh.
