"Textual Studies of Truyện Kiều" by Associate Professor Đào Thái Tôn is a meticulously crafted, high-value scientific work that is indispensable for anyone seeking to delve deeply into Truyện Kiều. Based on original texts and employing statistical methods to analyze the linguistic variations across different versions of Truyện Kiều, the author develops a methodological approach aimed at discovering “Nguyễn Du’s original words,” recognizing that none of the existing editions of Kiều are the poet’s original manuscript. In addition to providing facsimiles of the original Nôm text, the book includes annotations in original Nôm script where the text contains engraving errors or has suffered from deterioration over time. The author also points out that the degree of textual discrepancies is significantly greater in the Huế textual system compared to the Thăng Long system, offering valuable insights for determining which versions are closer to the original. The book also features important articles by the author addressing current controversies and misconceptions, such as disproving the existence of the so-called “Phường edition” (allegedly printed by Phạm Quý Thích) and refuting the idea of a “Kinh edition” of Truyện Kiều edited by Emperor Tự Đức. With its in-depth, carefully researched content, this book provides comprehensive information that helps readers gain a thorough understanding of Nguyễn Du’s Truyện Kiều. It is hoped that this work will serve as a valuable reference for scholars, cultural researchers, and anyone interested in Vietnamese literature.
