Inv. Scu 278
It is one of the numerous Roman copies of a statue of Athena made between the end of the 4th and 5th century BC, in which the goddess is wearing a long tunic (chiton) and a cloak; her head is covered by a Corinthian helmet and her right hand shows a preserved fragment of the spear that she held.
The most famous example of this type, kept in the Vatican Museums, is known as Athena Giustiniani . The ancient head is not the original of the statue, but belongs to the same type.
