First, the map shows two islands off the east shore of Ulleungdo labeled as 小于島 and 大于島, which is slightly different from a map in the National Library of Korea that labels the islands as 小干島 and 大干島. Another difference between the two maps is that the Samcheok Museum Map shows the following labels right next to the island labeled as 大于島:
- 苧田 (field of ramie)
- 倭船倉 (Japanese boathouse)
- 長沙仇味 (Jangsa Cove)
The Samcheok map shows the above labels right next to the island a fair distance from the shore, but the National Library of Korea map shows the above labels on or near the shore of Ulleungdo. I do not know what it means, but I have seen 倭船倉 written next to Usando (于山島) on a Korean map before, so maybe there was such a place on Ulleungdo's neighboring island. If anyone has any questions, just ask them.
I am a little disappointed that I could not get a good copy of the map for you, but I may go into Seoul tomorrow and try to find a book with the map in it. Anyway, it was not a wasted trip because I found something else that was kind of interesting that I will post about later.
