Circular Mirror with Well-Articulated Rim and Decoration of Two Pairs of Bowstring Lines

A well-articulated, concave lip borders the periphery of this circular mirror; the mirror's slightly countersunk back is flat and unembellished, save for two concentric pairs of intaglio bowstring lines that encircle small, hemispherical central boss (from which a silk cord would have been attached for holding the mirror or for attaching it to a mirror stand). The reflecting face of the mirror is flat and undecorated. A thin but even, celadon-green patina covers the mirror's decorated back; the same patina originally covered the reflecting face, though portions of that patina has been scraped away in modern times.
