The Prehistoric Patrimony Foundation of Venezuela, headed by Nieves Maria Rojas-Criollo, member of the La Salle Society of Natural Sciences since 1995; together with her husband, artist/photographer/explorer Marcos J. Criollo, Nieves has documented 470 parts of petroglyphs found in
Venezuelan territory and 600 petroglyphs from North, Central, and South America, and the Caribbean. We now offer our findings to the great national and international scientific communities; museums and other public and private institutions, and individual collectors. The petroglyphs can be acquired in coffers or wall paintings, both created with crystal-encrusted South American woods. Each item comes with all of the pertinent field information and other scientific data in both English and Spanish.

For order and commissions (build up your collection!), e-mail us or by phone: (401)4546674

Petryoglyphs are prehistoric signs etched into stone. In Venezuela about 470 petroglyphs have been found in different regions of the country. It is thought that the natives used tools made of quartz, silex or other equally hard stone. The technique used was certainly that of abrasion, wearing away the softest minerals through the process of rubbing. The unloosened stone powder, perhaps mixed with water, aided the process. The groove obtained is a U-shaped cross section, with the extremities somewhat more open at the base. This common form in Venezuela makes the glyphs more visible at those hours in which the sun illuminates tangentially the surface of the rock; during the rest of the day it is hard to distinguish them, as they are so illuminated they do not cast a shadow.
