Mona Lisa

"The Mona Lisa was, in fact, one of the world's most documented inside jokes."

The background behind her face is uneven.

Da Vinci painted the horizon line of the left significantly lower than the right.

He didn't screw it up.

By lowering the countryside on the left, Da Vinci made Mona Lisa lok much larger from the left side than from the right side.

Historically, the concepts of male and femaile have assigned sides -

Left: female; Right: male.

Because Da Vinci was a big fan of feminine principles,

he made Mona Lisa look more majestic from the left than the right.

And for the fact that: Da Vinci was a homosexual - A 'Fag'

Mona Lisa is neither a male nor female.

Carrying a subtle message of androgyny, it's a fusing of both.

There was this:

Egyptian God of Masculine fertility - Amon

+

Egyptian Goddess of Fertility - Isis

=

Mona Lisa

Her name is an anagram of the divine union of male and female.

That, is Da Vinci's little secret,

and the might also be the reason for Mona Lisa's knowing smile...
