Catalogue entry no. 505 by Max Loehr:
505 Openwork Plaque with Animal Mask
Very thin plaque carved of light grey jade with bluish black specks. A snake-like head in the center is joined to two body bands that spread to the sides and terminate in S -shaped, pointed tails which double back upon the bands. A slightly wider band frames the head and, passing under the snake bodies, ends above in two volutes. The snake’s bodies are textured by finely engraved hooks and curves; the wider band, by claw-shaped elements with criss-cross filling. A perforation is placed below the snake’s head, piercing the nose. The reverse side is plain; in the depressions on the carved side are traces of cinnabar and earth. Late Eastern Chou.
