In Context

“No memory of them both is more vivid than this mind’s eye picture of them at their evening meal in old age, engraved like an intaglio on a wall along one of the corridors of memory, two old people seen always in the roseate glow of sundown, caught forever by memory’s brush on a canvas only death can fade.”

August Derleth, Walden West, 1961.
