This mask, a grave deposit, is a masterful demonstration of naturalistic modeling. The sensitively carved features—drilled almond-shaped eyes with incised upper lids; straight, narrow nose with finely articulated and drilled nostrils; and the parted full lips outlined with an incised line—all suggest that this is a portrait. If it is a portrait it would be a precocious example of the genre in world art. The surface is adorned with incised motifs thought to have cosmological significance.
