My favorite picture is the 7th one.

I find it sad that leonardo was involved in creating weapons of destruction ♦♦ Certainly, I admired some of his other creative works/inventions (like the Flying Machine)

And his art, of course -- I like the drawings you show of his, near the end of your post - Bravo, for including so much detail & graphic work.

Thank u for a fine post [will likely re-steem ] ..

Have a good & productive wkend
