I have an alternative theory: the extremities of the statue are more delicate and the most likely parts to get knocked off over time. The size of the penis is probably proportional to the chance of it being knocked off, so we see fewer surviving examples of more endowed statuary. This theory doesn&#x27;t necessarily compete with the one in the article; canny sculptors may have gone for smaller dimensions to make their statues more robust as well as aesthetics.
