The objectives of this study are to confirm that Worincheongangjigok consists of a total of 583 songs, and to reconstruct the last songs (No. 582?583) of Worincheongangjigok along with the restoration of the damaged last part of Worinseokbo v.25.
The last part of Worinseokbo v.25 contains song No. 583 of Worincheongangjigok along with gloss, but because the part was damaged severely it is controversial whether No. 583 is the last song of Worincheongangjigok. Thus, Chapter II of this paper revised and supplemented existing evidences that Worincheongangjigok No. 583 in Worinseokbo is the last song, and presented new bibliographic evidences. The new evidences are the presumption that the number of missing pages at the end of the volume may not be much different from the number of missing pages at the beginning of the volume and the fact that the gloss in the last part of the volume has a different number of letters per line from that in the glosses for the part of Worincheongangjigok and for the part of Seokbosangjeol.
In this study, the reconstruction of the missing part of Worincheongangjigok No. 582 and 583 was based on the reconstructed contents of the last gloss in Worinseokbo v.25. As a result, it was found that narratives No. 1 and 2 of Worincheongangjigok are symmetrical to the last songs No. 583 and 582, but it was impossible at this point to reconstruct the last phrase of No. 583 of Worincheongangjigok. I expect further discussion on this phrase in future literary studies.
