Siebold Collection Maps' Historical Lineage with other Prefectural Maps in Edo Era

荷兰莱顿大学图书馆保存着德国医学博士冯·西博尔德(1796-1866)收集的21份手工复制的县地图。研究小组将这些地图带到了日本，以便制作高分辨率的数字化图像。通过与日本其他县县地图的比较分析，我们可以指出以下几个问题。在21幅地图中，1幅是在经济时代绘制的，6幅是在坎耶时期绘制的，14幅是在Syoho或Kanbun时期绘制的。我们可以证实一些地图的原始地图在日本的存在，尽管原始地图的制作时间不同。因此，我们推测冯·西博尔德与几个人有联系，这些人可以接触到手工制作的县地图。

Leiden University Library in the Netherlands keeps 21 hand-copied prefectural maps that was collected German medical doctor von Siebold, P.F.B. (1796-1866). Research group brought those maps to Japan in order to make high resolution digitalize images. As a consequence of comparative analysis with other prefectural maps in Japan, we can point out following matters. Out of 21 maps, 1 is drawn in Keicyo period, 6 are drawn in Kanyei-period, and 14 maps are drawn in Syoho or Kanbun period. We can confirm the existence of some maps' original one in Japan, though original maps' making periods are different. Thus, we presume that von Siebold had contacts with several persons who could access to hand-made prefectural maps.
