渤海文化与唐文化的关系是一个很富吸引力的学术问题。长期以来,不少中外学者致力于这方面的探讨。这个问题先是在历史学界提出,然后考古学界,影响到建筑史界。这篇文章以上京筒瓦和兽头为纵线,从横的角度把渤海瓦和唐瓦联系起来以比较研究的方式介入讨论。 The relationship between the Bohai Sea culture and the Tang culture is an attractive academic issue. For a long time, many Chinese and foreign scholars have devoted themselves to this aspect. This problem is first raised in the history of the academic community, and then archaeological circles, affecting the history of architecture. In this article, we use the above capitals and the beast head as the vertical lines to link the Bohai Sea and Tangwa from a horizontal perspective and discuss them in a comparative way.
