Answer: Ivory
Explanation: It's about the Chryselephantine statue of Athena. This statue was in the Parthenon on the Acropolis, more precisely between Propylaea and Parthenon. Parthenon served as a polytheistic temple, and which was a shelter of the statue of Athens. The Chryselephantine statue of Athena is predominantly made of gold and ivory 40 feet high or between nine and eleven meters high. The original statue of Athena no longer exists, but there are records of it as well as some of the smaller marble-made replicas. Athena was the patron of the city of Athens, revered as a deity.
