Nevertheless, in almost all the dolmens and later tombs mirrors of bronze were placed. This custom came into vogue in China at an early date, the mirror being regarded as an amulet against decay or a symbol of virtue. That Japan borrowed the idea from her neighbour can scarcely be doubted. She certainly procured many Chinese mirrors, which are easily distinguished by finely executed and beautiful decorative designs in low relief on their backs; whereas her own mirrors--occasionally of iron--did not show equal skill of technique or ornamentation. Comparative roughness distinguished them, and they had often a garniture of jingle-bells (suzu) cast around the rim, a feature not found in Chinese mirrors. They were, in fact, an inferior copy of a Chinese prototype, the kinship of the two being further attested by the common use of the dragon as a decorative motive. Bronze vases and bowls, simple or covered, are occasionally found in the Yamato sepulchres. Sometimes they are gilt, and in no case do their shapes differentiate them from Chinese or modern Japanese models. It might be supposed that in the field of personal ornament some special features peculiar to the Yamato civilization should present themselves. There is none. Bronze or copper bracelets,* closed or open and generally gilt, recall the Chinese bangle precisely, except when they are cast with a garniture of suzu. In fact, the suzu (jingle-bell) seems to be one of the few objects purely of Yamato origin. It was usually globular, having its surface divided into eight parts, and it served not only as part of a bangle and as a pendant for horse-trappings but also as a post-bell (ekirei), which, when carried by nobles and officials, indicated their right to requisition horses for travelling purposes. *Jasper also was employed for making bracelets, and there is some evidence that shells were similarly used. To another object interest attaches because of its wide use in western Asia and among the Celtic peoples of Europe. This is the penannular (or open) ring. In Europe, it was usually of solid gold or silver, but in Japan, where these metals were very scarce in early days, copper, plated with beaten gold or silver, was the material generally employed. Sometimes these rings were hollow and sometimes, but very rarely, flattened. The smaller ones seem to have served as earrings, worn either plain or with pendants.
