who created the cave paintings of altamira spain
Cave of Altamira Archaeological excavations in the cave floor found rich deposits of artifacts from the Upper Solutrean (c. 18,500 years ago) and Lower Magdalenian (between c. 16,590 and 14,000 years ago). Both periods belong to the Paleolithic or Old Stone Age. In the millennia between these two occupations, the cave was evidently inhabited only by wild animals. Human occupants of the site were well-positioned to take advantage of the rich wildlife that grazed in the valleys of the surrounding mountains as well as the marine life available in nearby coastal areas. Around 13,000 years ago a rockfall sealed the cave's entrance, preserving its contents until its eventual discovery, which occurred after a nearby tree fell and disturbed the fallen rocks.
Lascaux On September 12, 1940, the entrance to the Lascaux Cave was discovered by 18 year old Marcel Ravidat. Ravidat (died in 1995) returned to the scene with three friends, Jacques Marsal, Georges Agnel, and Simon Coencas, and entered the cave via a long shaft. The teenagers discovered that the cave walls were covered with depictions of animals.[7][8] Galleries that suggest continuity, context or simply represent a cavern were given names. Those include the Hall of the Bulls, the Passageway, the Shaft, the Nave, the Apse, and the Chamber of Felines. The cave complex was opened to the public on July 14, 1948.[9] By 1955, carbon dioxide, heat, humidity, and other contaminants produced by 1,200 visitors per day had visibly damaged the paintings. As air condition deteriorated fungi and lichen increasingly infested the walls. Consequently, the cave was closed to the public in 1963, the paintings were restored to their original state and a monitoring system on a daily basis was introduced.
