「涓滴落河流，只泛起一陣漣漪，就此而已；但滂沱大雨讓水面慢慢上升，洪水沖向下游，最終氾濫河堤。」——阿斯特紐斯（Astinus）
“A drop of water falling into the river causes a ripple on the surface, nothing more. But torrential rains will cause the water to slowly rise. The floodwaters progress downstream, and eventually the river will overflow its banks.”(p. 377).
