以下抜粋
ムカデ
Articulated centipede
Iron
Japan
Edo Period-Meiji Period, mid to late 19th century
Denys Eyre Bower Bequest 01.1043
The mukade, or centipede, is one of Chinese tradition’s ‘Five Poisonous Reptiles’, a creature in Japan generally associated with evil-doing but nonetheless possessing certain talismanic properties useful to ward-off misfortune. Because of these properties the insect is a commonly encountered subject in Japanese art and design. The present centipede is an okimono, or alcove ornament, with no particular function beyond the decorative. Though signed in the more sophisticated sosho, running, script and with a silver seal attached to the undersurface, the quality of manufacture is noticeably less sophisticated than other specimens among the Bower group, perhaps indicating a somewhat later, Meiji date for the piece.
雉
Articulated pheasant
Iron
Japan
Edo Period-Meiji Period, 19th century
Denys Eyre Bower Bequest 01.1045
There are two principal types of native Japanese pheasant: the smaller black-green kiji (the national bird), and the larger red-bown yamadori, both, on account of their distinctive mating call, symbolic of spring. This articulated and elaborately detailed iron model of the bird is of excellent quality and, while the wings possess only limited movement, the head turns and cocks its head in a convincingly naturalistic fashion. The piece is unsigned.
