How come on so many Roman statues or carvings the nose is gone?

The missing noses on many Roman statues and carvings are often the result of natural erosion, damage over time, or deliberate defacement. Noses are particularly vulnerable because they protrude from the face, making them more likely to break off due to impact or weathering. Additionally, in some cases, noses were intentionally removed, as part of ancient beliefs that defacing statues would "deactivate" their power or as acts of political or religious iconoclasm.
