英文摘要:A dragon pillar is an important part of Taiwan temple stone sculpture decoration. It not only plays a momentous role of weight bearing and partitioning the space, but also is the focus of vision of building façade. In Taiwan dragon pillars’ history of development, owing to the change of political power, the inscriptions of year/ era of previous dynasty were often altered, or the situations of “new sculpture on old works” happened. In the process of investigation, the author found that the style of rear-hall dragon pillars of Lu-Gang Tian-Hou Temple is of the later period of Cing Dynasty, but the inscriptions on the dragon pillars do not tally with the style of history division. Hence, whether this pair of dragon pillars are of “new sculpture on old works,” or works of antique imitation became a significant issue of this research. The purpose of this research is to explore the doubtful points of “works of imitation” or “new sculpture on old works” aroused by the inscriptions on the rear-hall dragon pillars of Lu-Gang Tian-Hou Temple. Therefore, the research started from materials and technics, and touched upon the process (working procedures) of stone works to be the foundation of analyzing the style (chapter II); then, the research discussed the period division of Taiwan dragon pillars to be the basis of analyzing the style of rear-hall dragon pillars of Lu-Gang Tian-Hou Temple (chapter III). Furthermore, the inscriptions of “Chang Hua Shih Lin Rong Chun Jing Sian (Donated by Lin, Rong-Chun of Changhua City)” would not be earlier than 1933, thus the relationships among Lin, Rong-Chun (person), the donation fact (matter), the year of donation (time), Lu-Gang Tian-Hou Temple (place), and the rear-hall dragon pillars (object) must be expounded in order to restore the circumstances of that very year (chapter V). Finally, cooperating with the conclusion of style analysis (chapter IV), the research sum up the crucial status of rear-hall dragon pillars of Lu-Gang Tian-Hou Temple in Taiwan dragon pillars’ history of development.
