Asturian language
Documents written in the Asturian language exist from as early as the 10th century, containing clear linguistic features of the language. However, significant numbers of documents in Asturian came into being only from the 13th century: writing by notaries, contracts, wills and the like. The importance of the Asturian language in the Middle Ages is revealed, for example, in the "Fuero de Avilés" (1085) (considered to be the first document written in Romanic) and the "Fuero de Oviedo", in the Asturian version of the "Fuero Juzgo" as well.
