Using an unconventional , 100 - older method acting , researcher have identify hidden animate being figures on the wall of a cave in Spain . The technique , called stereoscopic picture taking , dates back to the other 1800s but is perhaps well lie with for its use in the View - Master , the pre - VR witness beloved by generations of kids .
Cave paintings are a well - have it away and long - standing artistic culture medium in Europe , see back at least 40,000 year . Although archaeologists have studied this ancient artwork form for over a century , their focal point has typically been on the two - dimensional lineament of the designs and , when recording the graphics , they have relied on study , tracings and photographs .
After taking the cave wall’s contours into consideration, the researchers used the technique to reveal rock art depicting a horse. The bottom two images are processed with the computer software DStretch.
Recently , 3D transcription and viewing method have become popular among archeologist . These method enamor more rock candy graphics point than the 2D ones but are still typically viewed and studied as 2D images on a computer screen , which isnothow the art ’s creator would have seen it .
A new survey , published Aug. 17 in the journalAntiquity , change how archaeologists regard spelunk painting , with stereoscopic photographs of artistic creation from the cave of La Pasiega in N - central Spain .
Raquel Asiain , an archaeologist and photographer at Complutense University of Madrid , and her colleagues devised a bare method for capturing the three - dimensional nature of the cave walls and the art on it .
The photos show two previously unrecognized images in the cave. The bottom reveals those images after being processed with DStretch.

Pairs of high - resolution picture taken 2.5 inches ( 63.5 millimeter ) aside — the modal distance between an grownup ’s two pupil — can be see together , wedge the brain to comprehend a 3D image . While stereoscopic photo pairs are well seen with a viewing machine , the secret 3D epitome can also be spotted with the nude centre , similarly to those in the trippy " Magic Eye " pattern of the 1990s .
Over 700 word-painting of animals , symbol , dots and lines handle the wall of La Pasiega , which was first discovered in 1911 . But through their taxonomical study using stereoscopic photography , Asiain and colleagues hear three previously hidden animal : two horses and one Bos primigenius , an extinct cows species .
The horse cavalry are easy viewed in gamy - resolve images that the researchersposted to Flickr . The digitally enhanced double let on a sawhorse below the deer image in the inwardness , as well as the mane , neck and pectus of another sawhorse on the left . This latter horse is situated so that its head word rest in a concave area of the cave rampart , while the chest is in a convex area , enhancing the three - dimensionality of the animal .
Using 3D glasses , or even just by slightly crossing your eyes , it is easy to see theundulating lineament of the cave wallsjust as someone tenner of K of days ago might have seen it .
" In palaeolithic cave art , artists used the natural shapes of cave to create their painting , " Asiain tell Live Science in an email . " The need to keep up that 3D perception of the cave was one of the intellect that instigate me to utilize these stereoscope images . " With their high photographic quality , the figure let the research worker see the artistic creation in " real " 3-D , not simulated with 3D scanners .

" The proficiency these author employ is utilitarian for remind us how technically skilled these artists were and for giving us insight into the originative process,“April Nowell , an archeologist at the University of Victoria in Canada who was not need in the study , told Live Science in an electronic mail . bring out the stereoscopic images means the general public can come much near to experiencing the art as people would have in the past , Nowell said , but " you are still leave out the sound of dripping water , the cool dampness of the air . "
Asiain remains fascinated with the phylogeny of the cave artist ' techniques over time , particularly as " those creative person began to translate the stone as another element of painting . " She plan to comprise additional methods in the futurity to more fully understand palaeolithic cave art , such as whether ancient creative person manipulated and modeled the rock’n’roll , perhaps through carving , to create figures in 3D.
