简论燕下都半瓦当的错切现象

A Brief Discussion on the Miscut Semi-tile-ends Discovered on the Site of the Yan State Lower Capital

燕下都半瓦当均为范具压制当面纹饰。范具呈圆形，由两个相同且对称的图案构成，两图案中间留有一条较窄的切割线(图一)。制作时，将范具在当面泥坯上压制纹样，然后粘接于筒瓦坯的母口一端，再沿切割线由外向内切割，将其一分为二，最后烧制而成。

All the semi-tile-ends unearthed from the site of Yan State Lower Capital have a semicircular plan, which is shaped by dividing into halves the body made in a circular mold with design. In the process of making, some till-ends were miscut along the diameter vertical to the normal cutting line. This led to the formation of extraordinary designs, which draw attention for their rarity. Among the four types of miscut semi-tile-ends known so far, those with the so-called 'vertical eye, cloud, hydra and taotie mask design' and 'dancer figures in relief and integlio ' are improperly denominated and explained. In the present paper, the authors distinguish these mistakes and put forward their own views by analyzing related material and literary evidence.
