Old Leonese language

Old Leonese, Medieval Leonese, Medieval Asturian or Medieval Asturleonese was a West Iberian dialect of Vulgar Latin spoken in several regions of the Kingdom of León, including the medieval Principality of Asturias. It is the direct ancestor of current Asturleonese varieties. Old Leonese was spoken until around the year 1500, and was attested starting from the 10th century with the Nodicia de kesos.
