Why Did Ancient Greek Sculptures Have Such Small Penises?

Ever wonder why Greek depictions of their male heroes included powerful bodies and beautiful faces, but tiny penises?

Their physical ideals were not so dissimilar to ours, but for their symbolism of the penis. A large or erect penis in ancient Greece was associated with evil, stupidity, and/or poor self-control. In modern society, by way of comparison, a large penis is associated with power, desirability, and even competence.

Wouldnt it make more sense to judge and value people not on their genetic traits, but rather how they live their lives?
