More evidence Leo was a time-traveler
I especially like the end of this article:
Discovery Channel :: Da Vinci Invented Natural Plastics'It's interesting that Leonardo used layers ... to create unbreakable objects. In the case of oil painting, for example, linseed oil is the binding agent. This oil polymerizes slowly on contact with the air, forming a resistant, waterproof polymer similar to linoleum.
'This shows once again Leonardo's great innovative input--although obviously it doesn't add anything to our knowledge nowadays,' Alessandro Bagno, professor at Padova University's department of organic chemistry, told Discovery News.
