Matching Quote

"There were no clouds, the sun was going down in a limpid, gold-washed sky. Just as the lower edge of the red disk rested on the high fields against the horizon, a great black figure suddenly appeared on the face of the sun. We sprang to our feet, straining our eyes toward it. In a moment we realized what it was. On some upland farm, a plough had been left standing in the field. The sun was sinking just behind it. Magnified across the distance by the horizontal light, it stood out against the sun, was exactly contained within the circle of the disk; the handles, the tongue, the share—black against the molten red. There it was, heroic in size, a picture writing on the sun."

-Willa Cather
