36,狮子望柱头。十七孔桥(图36-40)。北京民间流传说,卢沟桥的狮子数不清,其实十七孔桥的狮子更多。

41,在学习望柱头的时候,我发现一个有意思的事情。用电脑把水平的栏杆变成斜坡栏杆,望柱和栏板的侧视图就都从正规矩形变成了平行四边形(图41),而我看见的玉带桥的斜坡栏杆,栏板是平行四边形,望柱却依然保持正规矩形(图42)。那么在实际生活里,斜坡栏杆的望柱会不会也有平行四边形呢?

42,玉带桥,望柱保持矩形。

43,哈哈,这是涵虚堂北侧八字台阶的栏杆,栏板和望柱都是平行四边形啊(图43-45)。所以说,古人其实很灵活,在一定的规矩下,进行了很多的变化,这些东西都是在初步学习古建之前毫无体会的。

45,涵虚堂超近距离全景接片儿,8张原始图。这是朝北的八字台阶。
