Abstract:Lu Xun’s life has inextricably been bound with the Han Dynasty portraits. From 1913 to the last period of his life,Lu Xun not only collected thousands of rubbings of the Han Dynasty portraits,but also sorted them up. Although he was not able to publish his collection of the portraits that he had carefully sorted up throughout all his life, he accumulated the knowledge about the portraits during his activities of collecting and arranging, which had a direct impact on his literary creation. The reasons that Lu Xun collected and arranged the Han Dynasty portraits so attentively include not only his own artistic interest but also his two other purposes. On the one hand, as an outstanding art of China, the Han Dynasty portraits had been overlooked in the Chinese society;on the other hand, the collecting and arranging of the portraits can provide reference for the construction of modern Chinese woodcut art. Lu Xun’s collecting and arranging of portraits of the Han Dynasty, is a manifestation of his efforts to promote and develop the traditional Chinese culture. The knowledge of the Han Dynasty portraits accumulated by Lu Xun includes three parts: external knowledge, internal knowledge and theoretical knowledge. The external knowledge mainly refers to the knowledge about the distribution areas of the Han Dynasty portraits and the background knowledge of the Han Dynasty portraits. The internal knowledge refers to the knowledge about life experience, characters, events reflected by the portraits, as well as their classification. The theoretical knowledge consists of various viewpoints of the study of the portraits such as the theme,style,achievements and so on.
