a hole in the roof that civilization decided was a feature, not a defeat

means A window set into a roof or ceiling to let daylight (and sometimes air) into the space below.

from A transparent compound of "sky" and "light," both old Germanic stalwarts of English — "sky" coming from Old Norse "ský," meaning cloud, and "light" from Old English "lēoht." The word arrived first not on rooftops but at sea: "skylight" originally named an opening in a ship's deck to send daylight below, before it climbed ashore and settled into the roofs of houses around the 18th century.
