Los refugios con eco inspiraron a los antiguos artistas rupestres

1/2. Among this set of cliff cavities at a site called Baume Brune, only the middle one (with the smallest opening) contains ancient rock art. It also has special acoustic properties that produce loud echoesM. DÍAZ-ANDREU.

Los antiguos artistas rupestres se sentían atraídos por las cámarascon eco. Los miembros de las primeras comunidades agrícolas de Europa pintaron imágenes en refugios rocosos donde los sonidos rebotan en las paredes y en el campo circundante, dicen los investigadores.

Los refugios de roca que carecen de estos efectos son transmitidos, al menos en el centro del Mediterráneo, informan la arqueóloga Margarita Díaz-Andreu, de la Universidad de Barcelona, ​​y sus colegas en el Journal of Archaeological Science de Julio. En los paisajes con muchos sitios potenciales de arte rupestre, “los pocos refugios elegidos para ser pintados eran aquellos que tienen propiedades acústicas especiales”, dice Díaz-Andreu.

Algunos cazadores-recolectores y grupos de agricultores estudiados durante los últimos dos siglos creyeron en los espíritus que habitan en las rocas y revelan su presencia a través del eco. Pero la evidencia acústica de propiedades especiales del eco en sitios de arte rupestre es rara. El equipo de Díaz-Andreu estudió dos sitios de arte rupestre en 2015 y 2016. Baume Brune es un acantilado de un kilómetro de longitud en el sureste de Francia. De 43 cavidades formadas naturalmente en el acantilado, sólo ocho contienen pinturas, que incluyen figuras treelike y animales de cuernos. El arte rupestre en el Valle de Ividoro, en la costa este de Italia, a  [...] psn.si/


Sound-reflecting shelters inspired ancient rock artists | Science News
Acoustic data suggest early European painters preferred echo chambers
Ancient rock artists were drawn to echo chambers. Members of early farming communities in Europe painted images in rock-shelters where sounds bounced off walls and into the surrounding countryside, researchers say.

Rock-shelters lacking such sound effects were passed up, at least in the central Mediterranean, report archaeologist Margarita Díaz-Andreu of the University of Barcelona and colleagues in the July Journal of Archaeological Science. In landscapes with many potential rock art sites, “the few shelters chosen to be painted were those that have special acoustic properties,” Díaz-Andreu says...

The acoustic qualities of a rock shelter may have been a key factor in its selection as a site for rock art and indicate a spiritual significance to the practice, according to a recent study, while scientists are also looking into whether some caves were chosen as artistic sites because of the view.

Professor Margarita Díaz-Andreu and Dr Tommaso Mattioli, both from the University of Barcelona, Spain, spent two years visiting rock art sites in France, Italy and Spain to compare acoustics and assess their relevance to the choice of location.

‘In a cliff such as Baume Brune (in Vaucluse, France), with 43 shelters, why were only eight selected to be painted?’ said Prof. Díaz-Andreu. ‘There are other apparently similar ones nearby that were left empty. Why?’...
