shadow 

A darkened area from which rays from a source of light are excluded. The shadow pattern cast by light (e.g. sunlight, ceiling fixtures) is such a common sight that if light shines from the opposite direction (e.g. from the ground upward) the normal shadow pattern will be reversed and so will perception; depressions will appear as mounds or vice versa. Shadows offer a cue to depth perception, as when trying to judge the shape of objects. See penumbra; depth perception.

And if they were in the habit of conferring honours among themselves on those who were quickest to observe the passing shadows and to remark which of them went before, and which followed after, and which were together; and who were therefore best able to draw conclusions as to the future, do you think that he would care for such honours and glories, or envy the possessors of them?
And if there were a contest, and he had to compete in measuring the shadows with the prisoners who had never moved out of the den, while his sight was still weak, and before his eyes had become steady (and the time which would be needed to acquire this new habit of sight might be very considerable) would he not be ridiculous?
To make sure, I looked for his shadow, and there it was, a shapeless blotch the girth of his body, (the sun was overhead), moving along the ground.
I saw the dark blotch move swiftly across the court, and a brilliant burst of vari-colored light moving with equal swiftness to meet it; and then shadow and flash came together and there was the sound of unseen blows.
