Twas the Night Before Christmas has been called 'arguably the best-known verses ever written by an American' and is largely responsible for some of the conceptions of Santa Claus from the mid-nineteenth century to today. It has had a massive effect on the history of Christmas gift-giving. Before the poem gained wide popularity, American ideas had varied considerably about Saint Nicholas and other Christmastide visitors. A Visit from St. Nicholas eventually was set to music and has been recorded by many artists.
