Giuseppe Arcimboldo's 16th Century Optical Illusions Will Blow Your Mind

Arcimboldo was born in Milan in 1524, and began painting stained glass window designs before transitioning to portraits.

Although from far away they resemble the human face, the artist's beautifully arranged compositions consist of fruits, vegetables, birds, books and other elaborately arranged objects. His unusual vision, exceptionally given the era of his creations, led many to believe Arcimboldo didn't just have a fanciful mind, but was possibly mentally ill. "A fine line separates sheer imagination from uncontrolled hallucinations," the New York Times expressed in a 2007 diagnosis of his works.
