RUTILATION — [Noun] A reddening or a reddish glow. From Latin rutilation-, rutilatio, from rutilare ("to glow red"), from rutilus ("reddish, golden red"). Unlike "rubescence," which charts the process of becoming red, or "incandescence," which denotes fierce, white heat, rutilation is the settled state of a deep, suffused crimson glow itself. It is the last coal in a dying grate, the coppery gleam on cooling iron, and the bloody luminance lingering on the horizon after sunset—the quiet afterglow of spent heat, a memory of fire made visible.
