対馬金剛院所蔵の高麗版『大般若波羅蜜多経』について――これまでの調査との比較を中心として――

抄録

The Mahāprajñāpāramitā sūtra of the Korean canon kept at the Kongō-in in Tsutsumi, Tsushima City, Nagasaki Prefecture, has postscripts of the Edo and Koryŏ periods.

This text has been investigated three times so far. First, a survey was conducted by Isao Nakajima in 1943, confirming 333 volumes at that time. Next, a survey was conducted by the Nagasaki Prefectural Museum of Tsushima History and Folklore in 1996, and about 163 volumes were confirmed. However, details are unknown. Finally, a survey was conducted by the Institute for Rice Culture in Waseda University in 2003, and 164 volumes were confirmed from a simple catalog.

We had the opportunity to investigate the volumes in September, 2017. 165 volumes were confirmed, a number different from those obtained by previous surveys. Therefore, in this paper, we examine the postscripts of the Edo period.

As a result, we can conclude that the set had 600 volumes in 1682, 361 volumes in 1943, and finally, comparing the 2003 and 2017 surveys, it is confirmed that there were differences in the number of volumes, perhaps due to errors or a difference in how the paper was counted.
