珍しい中期明代の青花磁器 水浮きシナン（航海羅針盤） - Ming Dynasty (1368-1644)

極めて希少な中国の青と白の瓷水浮 Sinan。古代中国の帆走船に搭載された航海用羅針盤で、明代中期の1430–1500年前後に遡る。

Drum-shaped body with central concave reservoir intended to hold water for floating the magnetized needle. The top surface is decorated with under-glaze blue prunus scroll patterns. Moulded beaded serrated rims run along upper and lower edges. The outer wall is painted with simple stylised floral motifs. Unglazed sandy base bears original spiral wheel-cutting traces of hand‑finishing.

Surviving water‑floating Sinan artefacts are highly scarce. This piece represents tangible physical evidence for ancient Chinese nautical technology and Maritime‑Silk‑Road history, a folk‑kiln practical navigation implement for ship‑board use.
