Today being an art critic is a full time occupation for some individuals. When/where does the concept of "art criticism" first come into being?
Clarify
I am NOT looking for a random person sharing a personal opinion. I am looking for a professional person or skill set, recognized by the public in general or an employer (such as the government) for their skill in rating/criticizing/censoring art. They raised payment in financial support or public recognition. We recognize Socrates as a philosopher because he was recognized by his peers (though I don't believe he was paid for the act).
