a cave near the city of Montignac in southern France (Dordogne Department).
La Mouthe was discovered in 1895 by the French archaeologist E. Rivière. It contains several cultural levels pertaining primarily to the Solutrean culture and Magdalenian culture of the Upper Paleolithic. A lamp made of sandstone was discovered. Deep within the cave, realistic representations of bisons, reindeer, mountain goats, a mammoth, and a woolly rhinoceros were found. Many of the pictures are engraved; some are drawn in mineral pigment. The discovery of La Mouthe encouraged extensive study in the late 19th and early 20th centuries of Paleolithic cave art.
