Upper Lorraine (northern France) Niderlant: Since the 12th century, Niderlant ("Low land") was mentioned in the Nibelungenlied as the region between the Meuse and the lower Rhine. In this context the higher ground began approximately at upstream Cologne. Les pays de par deçà: used by 15th century Burgundian rulers who resided in the Low Countries, meaning "the lands over here". On the other hand, Les pays de par delà or "the lands over there" was used for their original homeland Burgundy (central France). Pays d'embas: used by 16th century Habsburg ruler Mary, Queen of Hungary, meaning "land down here", used as opposed to her other possessions on higher grounds in Europe (Austria and Hungary). Possibly developed from "Les pays de par deçà". Netherlands Apart from its topographic usage for the then multi-government area of the Low Countries, the 15th century saw the first attested use of Nederlandsch as a term for the Dutch language, by extension hinting at a common ethnonym for people living in different fiefdoms. This was used alongside the long-standing Duytsch (the Early Modern spelling of the earlier Dietsc or Duutsc). The most common Dutch term for the Dutch language remained Nederduytsch or Nederduitsch until it was gradually superseded by Nederlandsch in the early 1900s, the latter becoming the sole name for the language by 1945. Earlier, from the mid-16th century on, the Eighty Years' War (1568–1648) had divided the Low Countries into the northern Dutch Republic (Latin: Belgica Foederata) and the southern Spanish Netherlands (Latin: Belgica Regia), introducing a distinction, i.e. Northern vs. Southern Netherlands; the latter evolved into the present-day Belgium after a brief unification in the early 19th century. The somewhat dated English adjective "Netherlandish", meaning "from the Low Countries", is derived directly from the Dutch adjective Nederlands or Nederlandsch. It is typically used in reference to paintings or music produced anywhere in the Low Countries during the 15th and early 16th centuries. There are works of art that are now collectively called "Early Netherlandish painting", although the term it aspires to replace, namely "Flemish primitives", remains in use. In music the Franco-Flemish School is also known as the Netherlandish School. Later art and artists from the southern Catholic provinces of the Low Countries are usually called Flemish and those from the northern Protestant provinces Dutch, but art historians sometimes use "Netherlandish art" for art of the Low Countries produced before 1830, i.e., until
