black disc

Then a kind of black disc appeared in the middle of the world and rushed out to the edge of things and blotted them out.

Men looking up, near blinded, at the star, saw that a black disc was creeping across the light.

Perhaps one black disc of your beastly glasses is quite close and another fifty miles away.

In the center of a black disc she saw only the mocking eyes and evil face of Mullendore.

It is a kind of aureole, or halo, pearly white in colour, which is seen to surround the black disc of the moon.
