"The Rattlin' Bog" is an Irish folk song. It is a version of an internationally distributed folk song type. In the Roud Folk Song Index it has the number 129, and carries such titles as "The Everlasting Circle", "The Tree on the Hill", "The Green Grass Grew All Around", and "Down in the Lowlands", as well as "The Rattlin' Bog", The adjective rattlin' means "splendid" in the context of this song. It is a cumulative song, similar to "The Twelve Days of Christmas", as it has a list at the end of each verse which grows throughout the piece. The Roud index lists 180 versions collected from oral tradition in English, and the song has analogues in French, Italian and German as well. Since it is a folk song, it has been transmitted over generations orally and aurally so many versions coexist and it may be impossible and even nonsensical to seek a single authoritative version of the song's lyrics. The earliest version appears to be "March to the Battlefield" in "Riley's Flute Melodies" published by Edward Riley. In 1877, water-colour painter and folk-song collector Miss Marianne Harriet Mason published a version called "Green Grass Grows all Around" in "Nursery Rhymes and Country Songs".
