Whoa. That's pretty rad! Why don't more people know about this guy? Considering he predates the surrealists by literally hundreds of years, you'd think he would get more press. This stuff would be right at home in an issue of Juxtapoz magazine.
Striking, isn't it? I ran across his work when taking cog psych/cog neuro courses. Arcimbaldo's paintings provide a great demonstration of face perception and — one could argue — face-seeking that our brains perform with no conscious effort.
Just to say, he's quite well known amongst artists and art historians, though I don't recall learning about him in my Western art history course. Along similar lines, but more well known is Hieronymus Bosch http://lmgtfy.com/?q=hieronymus+bosch.
