In the center of the scene, the two Boreads, Zetes and Kalais, chase the two-winged Harpies to free Phineus from his punishment. They wear short chitons and have their swords belted. Although they do not have wings, they wear winged shoes. One Boread has grabbed a Harpy by the hair. The Harpy holds the food she has just stolen from Phineus. The other Boread pulls his sword out of its sheath to behead her. The two Harpies fly to the right, trying to escape. To the left, a woman is gesturing and turning back, perhaps to announce to blind Phineus his salvation. Only the hand of Phineus is preserved. It can be seen on the table, searching for food.

This ivory relief was restored by 45 fragments, which were collected from two deposits (garbage pits) of the sanctuary, located between the Corinthian Treasury and the Stoa of the Athenians. In total, 2,000 ivory objects were found in the deposits along with many other findings! The relief comes from the coating of a wooden or bronze box, furniture, or throne. It was kept in one of the Treasures (buildings in the sanctuary, dedicated by the cities, where precious objects/dedications were kept). Τhere are also traces of gilding.
