Thanks...

I think the point Cal was making is that the Roman Empire was expected to last forever, and Christianity was going to die out quickly.

While Rome was pagan, the Colosseum thrived. It was the Christians who vandalized it because they saw it as a pagan building and need stone for construction. The poster was using the Colosseum as a symbol of the fall of the empire, and the rise of Christianity, when it was Christian Romans who tore some of it down.
