敦煌本景教《志玄安乐经》佐伯录文质疑

Questioning Saeki's Restoration of the Dunhuang Document Nestorian Chih Hsüan An Lo Ching

《志玄安乐经》是２０世纪初敦煌出土的唐代景教写本，原件自始便为藏书家李盛铎私人所占有，后来又被其贩卖给日本人，直至１９５８年才有局部照片披露。该件录文于１９２９年由 日本羽田亨博士刊布，１９３４年佐伯好郎博士重新制作录文刊布并加英译；当今学界流行的该写本录文多源自佐伯文本。文章就该写本录文的刊布过程进行了追踪考察，指出佐伯文本不符合古文书整理的规范，其中存在若干失误，认为在原写本未公开展示之前，对该经的专门研究应依据羽田最早发表的录文。

Discovered in the early 20th century at Dunhuang, Chili Hsüan An Lo Ching is a Nestorian manuscript of the Tang Dynasty. Since its discovery it had been possessed by Li Shengduo, an independent book-collector. Laier it was sold to some Japanese, and not until 1958 were photographs of part of its content released. In 1929, the manuscript was transcribed and published by Dr. T. Haneda in Japan. In 1934, the ancient copy was restored and published by another Japanese scholar, Dr. P. Y. Saeki, who also translated it into English. It is upon Dr. Sacki's restoration that most versions of the manuscript are based. This paper traces the publishing process of the original manuscript, pointing out that Saeki's version does not accord with standard procedures of ancient documents restoration, and it contains some errors. It is held that before photographs of the full content of the original manuscript are released, studies concerning the manuscript should be based on Dr. Haneda's transcript first published in 1929.
