Catalogue entry no. 600 by Max Loehr:
600 Ornament in the Shape of an Arc
Opaque grayish brown, rather soft stone in the shape of an approximately semi-circular segment with an extension doubled back upon the outer arc. One face is plain; the other is decorated with a shallowly incised pattern of angular meander motifs and parallel grooves. The left end, with its peculiar notched outline, set off by a transverse, rope-like band, suggest an extremely conventionalized animal head. The opposite end, accordingly, may represent a tail. The mouth is indicated by a thin, wiggly, sawed-out line, a technique not paralleled in this collection. The edges of the rest of the extension beyond the “head” are very coarsely and unevenly treated. While reminiscent of Eastern Chou types, this object, which for once lacks all sensuous appeal, appears to be of later date.
