Why are the penises of ancient Greek and Roman statues so small?

First of all, this is a weak state. If you compare them with the dormant penises of most men, you'll find that they're not much smaller than they actually are. Secondly, in different periods, people’s aesthetics towards men are also very different. Maybe in today's era, "big roots" will be considered a symbol of masculinity and worshiped, but most of the evidence shows that in ancient Greece, smaller sizes were more popular. There is another important reason in ancient Greece. In culture, a large penis represents "stupid", "obscene" and "ugly".
