Thank you Pacifist and Yabutarou,Yes, 右 does look like 古, so that may be possible, but if that were true, then I think they would have wrttien 于山國, not just 于山.Korean dictionaries say that 右 can also mean "west" (서쪽). See . Also, Kim Jeong-ho's maps tell us that he believed Usando to be east of Ulleungdo, which would mean that Ulleungdo would be west of Usando.Anyway, remember that I am just guessing. I do not know for sure.,ozLAHSbFhsR,
