Shadow
A shadow is an area where direct light from a light source cannot reach due to obstruction by an object. It occupies all of the space behind an opaque object with light in front of it. The cross section of a shadow is a two-dimensional silhouette, or reverse projection of the object blocking the light. The sun causes many objects to have shadows and at certain times of the day, when the sun is at certain heights, the lengths of shadows change.

Bodies of shadow and blind eyes like pearls,
Came up out of the hole, and red-eared hounds
With long white bodies came out of the air
Suddenly, and ran at them and harried them.”

Broke shadow into all its parts,
What then had been of shadow made
Found exigence in fits and starts....”
