Asturian (asturianu)

Asturian, which is also known as Bable, is a Romance language spoken
by about 550,000 people in parts of Asturias (Asturies) in the
north of Spain. Asturian is very closely related to
Mirandese and was influenced by the pre-Roman
languages spoken in the Asturias region.

Asturian first appeared in writing in 1155. It was used in official
documents until the 14th century, when it started to be replaced by
Spanish. It was also used to some extent in literature during this
period. Between the 14th and 17th centuries, writtten Asturian
disappeared from official documents and was only used informally.
During the 17th century there was a literary revival started by
Anton de Marirreguera.
