This story has been circulating the internet for awhile. It is not original to steemit. Your other post is also a plagiarism of another site. I downvoted that one, but won't this one because here at least you wrote your own work. Obviously you don't know all this info first hand, so you should have links down at the bottom to where you got your info from.

I would suggest you stop plagiarizing other people's work.

I have been doing a series on Leonardo, so I know what I am talking about.
