唐代鉴真大师六次东渡,不仅是弘扬佛法的盛举,也是盛唐时期经济文化的全面传播。在学术界有关鉴真的研究,举凡文学、美术、工艺、建筑、医药、饮食诸多方面,都有较为全面而深入的研究。然而对于其中涉及有关货币的问题,如鉴真东渡使用的是什么货币,采办物资花费多少,旅途上携带多少资金等问题,仍然付之阙如。本文围绕鉴真东渡的基础史料《唐大和上东征传》,列举了《东征传》中的货币史料,对其体现的唐代货币发行制度、货币流通状况、钱币版别和中日货币文化交流等问题进行了全面分析。 The master of the Tang Dynasty made six trips to Dongdu, which was not only a grand ceremony to promote Buddhism but also an all-round dissemination of economic and cultural resources during the Tang Dynasty. In the academic community on the study of jianzhen, where all literature, art, crafts, architecture, medicine, diet and many other aspects, there is a more comprehensive and in-depth study. However, the questions concerning the relevant currencies, such as what currencies are used in the authentication of Dongdu, how much money is spent on the procurement of materials, and how much money to carry on the road, are still missing. This essay focuses on the basic historical materials of Tang Du and Shang Dong Zheng Zhuan, and cites the historical materials of money in “The Legend of the Eastern Zheng Dynasty”. It gives a brief account of the monetary circulation system, currency circulation, coinage, Currency and cultural exchange issues such as a comprehensive analysis.
