'Lays of Ancient Rome' is a collection of narrative poems, or lays, by Thomas Babington Macaulay. Published in 1842, these poems depict heroic episodes from ancient Roman history, drawn largely from Livy, with the aim of demonstrating the virtues of republicanism and duty. The collection includes famous incidents like the story of 'Horatius at the Bridge', and is written in a vivid, energetic style that embodies Macaulay's passion for the classical world.
