Small part of a raking cornice from poros limestone that comes from the archaic Parthenon or Hekatompedon. Its back side is sculpted rudimentary and preserves tool marks, while its right side has anathyrosis.

The cornice’s front side is decorated with alternating red and blue scales. These belong to the outstretched left wing of an aquatic bird that was depicted. The bird is most likely similar to those shown on other parts of the cornice such as the fragments Ακρ. 22, Ακρ. 22 α and Ακρ. 22 β from the decoration of the same archaic building.
