關於琉球《選日通書》及新發現的韓國國立中央圖書館藏本的價值

On Newly Identified Copies of Ryukyu Calendar Xuanri Tongshu

琉球《選日通書》是琉球王國根據清朝《時憲書》並結合琉球獨特的風俗、習慣而編制的官製曆書。近代以後，琉球王國文獻資料遭到毀滅性破壞，現存的琉球《選日通書》已寥寥無幾。2013年7月，筆者在調查韓國國立中央圖書館舊朝鮮總督府藏書時發現了8種以前學界未知的琉球《選日通書》，無論從琉球王國漢文文獻的基本調查的角度還是從琉球曆書研究的角度來看，都具有重要意義。本稿在對現存琉球《選日通書》調查基礎上，結合相關史料記載，考察琉球王國編撰曆書的歷史、琉球《選日通書》與清代《時憲書》的關係，並對琉球《選日通書》的內容以及中央圖書館藏《選日通書》的特徵及其價值進行分析。

Xuanri Tongshu is an official calendar published by the Ryukyu Kingdom. It is based on Qing China's Shixian shu (state calendar of the time), while also taking into the elements of Ryukyu's own customs and traditions. Because many texts of the Ryukyu Kingdom have been lost after entering the modern era, not many copies of Xuanri Tongshu have been identified. The author of this paper recently found eight copies of this book, which haven't been identified before, in the collection of the former Governor-General of Korea, preserved today in the National Library of Korea. These newly found materials are of great value both to the research on Chinese texts in Ryukyu as well as to the research on Ryukyu calendrical books. Drawing from the preliminary research on current extant copies of Xuanri Tonhgshu and related historical materials, this paper first provided an overall history of calendrical books compilation in Ryukyu, then analyzed content of Xuanri Tongshu, together with its the relationship to Qing China's Shixian shu. Through these analysis, this paper shed light on the characteristics and importance of Xuanri Tongshu preserved in the collections in the National Library of Korea.
