Even so, when a sunbeam is reflected in water, the light flits to and fro through the room, quivering as the reflection moves, and strikes the ceiling with flickering shadow.

Book VII, lines 142–145 | Compare | Sicut aquae tremulum labris ubi lumen aenis sole repercussum aut radiantis imagine lunae omnia pervolitat late loca, iamque sub auras erigitur summique ferit laquearia tecti. | As quick as flickering light thrown off by water in bronze bowls reflects the sun or radiant moon, now flittering near and far, now rising to strike a ceiling's gilded fretwork. | Virgil, Aeneid (19 BC), Book VIII, lines 22–25 (tr. Robert Fagles)
