P3D 3d Art Before Photography

["Sokolowski, Ray" <paa5402@xxxxxxxxxxxxxxxxxxx>]

In "Photographing in 3D" from Reel 3D, the author mentions that an
ancient Greek (can't remember his name) was the first person to notice
that each eye saw a slightly different image. ( I'm sure he wasn't the
first person in the world who ever noticed this, but maybe the first to
write it down. I noticed it as a kid.)
They also mention that there were some drawings or paintings done before
the advent of photography which displayed this phenomena. Does anybody
know what these paintings are?
