The Mattei Athena is a Parian marble sculpture dating to the 2nd or 1st century BC.

The statue has several areas of damage, including to the head, which had been broken at the top of the neck.

The Mattei Athena's left hand and wrist are also part of a modern restoration, but it is considered likely that they matched the Piraeus Athena originally.

This difference is attributed by scholars to economic and technical reasons.

To carve the right arm extending forward would have required more marble, and the arm might not have been strong enough to hold something, as it is believed the Piraeus Athena originally did.
