Why Dark Horse
This region of dark nebulae is called Dark Horse because it resembles the side silhouette of a horse and appears dark as compared with the background glow of stars and star clouds. It is also known as "Great" because it is one of the largest (in apparent size) groups of dark nebulae in the sky.

“A book is a part of life, a manifestation of life, just as much as a tree or a horse or a star. It obeys its own rhythms, its own laws, whether it be a novel, a play, or a diary. The deep, hidden rhythm of life is always there—that of the pulse, the heart beat.”
—Henry Miller (1891–1980)
