COLUMNS or SHADOW PEOPLE

An interesting example of classical architecture, isn't it? Take a second look between the columns and you'll see the silhouette of three groups of people talking to each other. How unusual! At first, it can be tough to see d shadowy figures in this illusion, bt once your brain figures it out, it has a hard time seeing the columns.

What do you think they are talking about? Do they know they've been obscurely sculpted into a piece of history? I bet not. I wonder how that makes them feel.
