Light engravings-a very common Pleistocene technique-are notoriously difficult to see. Until it re-emerged on our computer screen, this 64,000 year old hand stencil remained undiscovered despite 70 years of intensive study in the cave.

We photographed the area and then used digital image enhancement software which revealed the hand stencil very clearly. The stencil had been obscured by the build-up of calcium carbonate deposits.

The hand stencil is clearly visible (middle right). Below is a hand stencil in the cave of Maltravieso (Estremadura, western Spain) which was not immediately apparent when we were searching the cave for suitable samples to date its art.ĭigital photograph of hand stencil (GS3B) in Maltravieso Cave, unenhancedĭigital photograph of GS3B after image enhancement using DStretch software. One example critical to our own research only came to light through digital manipulation of images that we took of it.

Some 500 European caves are known to contain rock art from the Pleistocene era between 2.6 million and 11,700 years ago. Rock art in the dark zone of caves beyond the natural light in cave mouths was only discovered in North America in 1979, more than a century after its discovery in Europe (at Altamira in northern Spain). Assuming more art does survive, the chances are we may never see it unless we invest in research and new technologies. Pigments can dull and disappear thin engravings can erode to nothing and cave walls can crumble or be covered over by crusts of carbonate deposits or mud. It is likely that we know of only a tiny percentage of the rock art created in the past. Rock art is found on almost every continent, and the earliest is at least 64,000 years old. It allowed Professor Simek's team to 'lower' the cave floor up to 4 meters, enough for the complete motifs to come into view for the first time. Photogrammetry is a cheap technique increasingly used in archaeology to record artifacts, buildings, landscapes and caves. They were revealed only through a technique called photogrammetry, in which thousands of overlapping photographs of an object or place are taken from different angles and digitally combined in 3D. The cave ceiling is only 60cm high, which makes stepping back to view the large images impossible. This was also in accord with the age of pottery fragments ancient artists left in the cave. This left a residue that the researchers were able to date with radiocarbon to 133–433 AD. In terms of dating the findings, ancient people rejuvenated a light in the cave (a flaming torch of American bamboo) by stubbing it against the cave's wall. Optically Stimulated Luminescence ( OSL dating) on examples in the Wadi Wisad region suggest they were built in two main pulses, one in the Late Neolithic about 8,500 years ago and one about 5,400 years ago during the Early Bronze Age-Chalcolithic.Human figure (1.81m tall). The kites and associated walls (called desert kites) are thought to be mass kill hunting tools wheels (circular stone arrangements with spokes) appear to be constructed for funerary or ritual use, and pendants are strings of burial cairns. They are classified into four main categories based on their shape: kites, meandering walls, wheels, and pendants. First brought to scholarly attention by RAF pilots flying over the desert shortly after the Arab revolt of 1916, the geoglyphs were made of stacks of basalt, between two to three slabs high. In the Black Desert of Jordan, ruins, inscriptions, and geoglyphs are called by the Bedouin tribes who live the Works of the Old Men. Hundreds of thousands of geoglyphs are known in or close to lava fields throughout the Arabian peninsula.
