Sobre Dibujos de Arte Rupestre (Andino)

logo-tracceThe essence of every rock art study must be the image. In most cases the image that we observe is not quite the same as manufactured and/or intended by prehistoric people. It is altered by weathering, erosion and all sorts of anthropic activities. Yet, the resulting image is the only source to use. The best thing to do is to photograph the image, but if one makes a drawing of the image, it should be as correct as possible. Yet, many rock art researchers produce and publish drawings that are not correct. Consequently, their interpretations will be incorrect. This study discusses some examples of incorrect drawings and offers some recommendations.

AsTrend, ancient carvings enhanced

AsTrend

AsTrend

A short outline of a new low cost methodology: we present the AsTrend, a new methodology for enhance and depict details of the 3D models. This technique is being revealed as an accurate method to study rock art carvings and inscriptions. We think that this method could be used by everyone as the main study objects are based in low cost photogrammetry on the acquisition of 3D models.

Rock Art in Jebel Akhdar, Oman

Bilad Sayt

Bilad Sayt

The petroglyphs and pictographs of Oman are little known, but for the last five years I have been involved in a series of surveys of the Jebel Akhdar Mountains that have resulted in the location of several important sites. Recording these in advance of construction projects undertaken to modernize the country’s transportation network has enabled me to study the rock art in considerable detail for the first time. Using superimpositions, cross-dating with known artistic expressions elsewhere in the region, and the known dates for introduction of various objects of material culture, I propose a preliminary chronology consisting of four major phases spanning the last 6,000 years.
