the tenuous reflection of luminous insects

"Then, for more than ten days, they did not see the sun again. The ground became soft and damp, like volcanic ash, and the vegetation was thicker and thicker, and the cries of the birds and the uproar of the monkeys became more and more remote, and the world became eternally sad. The men on the expedition felt overwhelmed by their most ancient memories in that paradise of dampness and silence, going back to before original sin, as their boots sank into pools of steaming oil and their machetes destroyed bloody lilies and golden salamanders. For a week, almost without speaking, they went ahead like sleepwalkers through a universe of grief, lighted only by the tenuous reflection of luminous insects, and their lungs were overwhelmed by a suffocating smell of blood. They could not return because the strip that they were opening as they went along would soon close up with a new vegetation that almost seemed to grow before their eyes." One Hundred Years of Solitude
