S1987.887
This tall, ten-tiered cong 琮 shows obvious tapering from top to bottom. Its surface is worn but the fine meanders instead of the parallel lines that fill the headbands are still visible. The ledge marking the imperfect meeting of the drillings from both ends is clearly seen on the inside wall. The high collar also shows a squared outlined.
It is one of the few examples that shows an even number of tiers. The lack of mathematical precision in the height for each tier--ranging from 2.22 to 2.44 centimeters high--would suggest that the division was done perhaps by sight rather than with the help of any instrument.
