Acquired about 1963.

Physical Description

This helmet bowl has a tall skull embossed from a single plate in the form of half an abergine. The upper section of the skull is further embossed outwards to represent the pointed sections of the calyx or sepals, with the stippled surface providing detail. At the apex the plate is drawn out into a hollow stalk, which serves as a tehen (hole in the crown of a helmet bowl occuring at the top of most Japanese helmets). Forming part of the main plate is a peak, embossed to represent two half leaves with veins, lacquered red underneath. Rivetted to the lower edge of the bowl is an almost flat koshimaki (strip of metal or flange riveted to the lower edge of a helmet bowl), pierced in three places with single holes for attaching a shikoro (neck guard). The whole outer surface has been covered with sawari (silver coloured alloy used as decoration in the form of droplets) which appears to have been rather over-heated, with the result that the alloy has spread rather than remaining in droplets.

Since Ryoei apparently did not tend to sign his work with the Myochin name, his relationship to that group is not really known. Most of his work was unsigned, as is the case with this helmet.
