onze was known and practised during twenty centuries
prior to the Christian era; but although Japan seems to have
possessed the knowledge at the outset of the dolmen epoch, (circ. 600
B.C.), she had no copper mine of her own until thirteen centuries
later, and was obliged to rely on Korea for occasional supplies. This
must have injuriously affected her progress in the art of bronze
casting.

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
