You've heard I suppose, long ago, How the snakes, in a manner most antic, He marched to the county Mayo, And trundled them into th' Atlantic

These lines play on the familiar Irish legend of St Patrick banishing snakes from Ireland, recasting it in a deliberately comic, sing-song manner (“most antic,” “trundled”). The diction suggests a mock-heroic tone: a grand national miracle is narrated as if it were a farcical local errand, complete with a specific Irish place-name (“county Mayo”) and a physical, almost slapstick action (“trundled…into th’ Atlantic”). The effect is to puncture solemn mythmaking and to foreground how legends are transmitted as catchy, easily parodied verse. It also hints at the way Irish themes were often treated in nineteenth-century British/Anglo-Irish periodical satire.
