On what was the Mona Lisa painted?

I think the Mona Lisa must be the most overrated painting in history. I love art and studied art history but I've never understood what all the fuss is about.

Probably the world’s most recognisable face.

LaContessa, I have read that the reason it is so famous is because it was stolen. Just what I read.

Tammey, yes, and I believe that they have it behind the wall of glass and security stuff

she really isn't that beautiful and I've seen this painting and I'm not even sure if it's real,, in the Louvre. I'll guarantee that they have it sitting around some place that's safe

LaContessa, The painting garnered a lot of notoriety when it was stolen from the museum in 1911. That's when it started becoming famous worldwide.

nolongerIbutCHRIST, There is a theory that Leonardo couldn't part with the painting because it's himself.

nolongerIbutCHRIST, Bad Form!

so, it was painted on a wooden panel? why do I think it would be on canvas?
