Catalogue entry no. 533 by Max Loehr:
533 Large Ornate Disk
Magnificent, heavy piece, cut from an evenly thick slab of moderately translucent, variegated bluish green and greenish gray jade. As in No. 531, the design, identical on both sides, consists of an outer zone with a design of four animal heads and curvilinear bodies, and a broader inner zone of relief hexagonal units. Here, however, the hexagons bear incised spirals. On either side of the inner zone are two circles, suggesting loosely twisted ropes. Compared with No. 530, the design of the “bucraniums” is simplified, and instead of the overlapping, wing-like elements there appear S -shaped figures with bird heads. The execution of the grooved outlines is less careful than in the case of No. 531. Late Western or early Eastern Han.
