The roots of written Gallo literature are traced back to "Le Livre des Manières" written in 1178 by Etienne de Fougères, a poetical text of 336 quatrains and the earliest known Romance text from Brittany, and to "Le Roman d'Aquin", an anonymous 12th century chanson de geste transcribed in the 15th century but which nevertheless retains features typical of the mediaeval Romance of Brittany. In the 19th century oral literature was collected by researchers and folklorists such as Paul Sébillot, Adolphe Orain, Amand Dagnet and Georges Dottin. Amand Dagnet (1857-1933) also wrote a number of original works in Gallo, including a play "La fille de la Brunelas" (1901).
