“Menacing lines of black tomorrows on the horizon.”

“Tomorrow was over the horizon, and would take an entire day to reach.”

“Earth gravity and a line of horizon is how we, as Earth humans, are accustomed to gauging spatial orientation.”

“When man does not have firm, calm lines on the horizon of his life- mountain and forest lines, as it were- then a man's innermost will becomes agitated, preoccupied, and wistful.”

“Here today, up and off to somewhere else tomorrow! Travel, change, interest, excitement! The whole world before you, and a horizon that's always changing!”

“Between the black of yesterday and the white of tomorrow is the great gray of today, filled with nostalgia and fear of the future.”

“Gentlemen, I would rather have written those lines than take Quebec tomorrow.”

“The rain has lifted enough so that we can see the horizon now, a sharp line demarking the light grey of the sky and the darker grey of the water.”

“Sometimes I wonder, laying in a great black stripe on a canvas, what animal bones (or horns) are making the furrows of my picture… black grows deeper and deeper, darker and darker before me. It menaces me like a black gullet. I can bear it no longer. It is monstrous. It is unfathomable. As the thought comes to me to exorcise and transform this black with a white drawing, it has already become a surface.”

“Lo — a black line of birds in wavering thread
Bore him the greetings of the deathless dead!”
