Help with very hard riddle

Leonardo da Vinci

nope, sorry.

Lucius Domitius Ahenobarbus

also known as, the emperor Nero? Nope, not him either. Nice try though..
keep trying!

Puzzling.
The emperor Nero built the Golden House in Rome. When the Golden House was built over, it was rediscovered very early in the Renaissance period and several famous renaissance artists left their graffiti there. Leonardo discovered many things (sound ??), the smirk is the Mona Lisa, was he a boy when the Golden House was discovered (??) no-one thought he was Greek, but his first language was Italian.
So ended my first two thoughts.
Lucius Domitius Ahenobarbus lived as a boy in the Golden House and thats all I know of him.

There is another Golden House in Venice.

Can I ask a question ? (that one didnt count)

No. Nero built the Golden House so he couldnt have lived in it as a boy. There were several by that name and similar names. It was a frustrated guess...

Domenikos Theotokopoulos

Leonardo di ser Piero da Vinci

Hey! No Fair ! I said that one .

Oops ! Sorry. I Didn't See Your Answear.
In Any Case, It's The Wrong Answear.

Tiziano Vecelli

Renaissance Man

demeter greek god of language

Sorry for not replying for such a long time.
None are correct so far.

Here is another clue:

Clue 4: It was the 1700's and Anatomy was the game. Some would say that he has a typical Italian name.

Here are all the clues so far..

CLUE 1: TODAY WE HAVE A MYSTERY ABOUT A MAN IN HISTORY. OF THE MANY THINGS HE FOUND, ONE IS RELATED TO SOUND.

CLUE 2: As a boy, in the Golden House he would lurk. As a man he discovered the smirk.

CLUE 3: Some think he hails from the isles that are Greek. But, Italian was the first language he could speak.

CLUE 4:It was the 1700's and Anatomy was the game. Some would say that he has a typical Italian name.

Who/What is it?

George Adams Jr. I got it from some website but the only thing that fits is that he musical instuments.

Mona Lisa is the what?
