Here's why:
* Metaphor: A figure of speech where a word or phrase is applied to an object or action to which it is not literally applicable.
* Shafts of light are usually used to describe beams of light coming through narrow openings, like sunlight through a window or a doorway.
* Pools of light are used to describe areas of light that are concentrated and still, like the light from a lamp or a spotlight.
The phrase "shafts and pools of light" combines these two images to create a more vivid and descriptive picture of light. It suggests a scene where light is both focused and scattered, creating a sense of depth and drama.
Here are some examples of how this phrase might be used:
* "The setting sun cast shafts and pools of light across the deserted beach."
* "The city lights below shimmered like shafts and pools of light in the darkness."
* "The stained glass window in the cathedral created beautiful shafts and pools of light on the floor."
These examples show how the phrase "shafts and pools of light" can be used to create imagery that is both beautiful and evocative.
