Featured Article: Petroglyph

Lion Petroglyph, Twyfelfontein, Namibia.
Petroglyphs are images created by removing part of a rock surfaces by incising, pecking, carving, and abrading. Petroglyphs are found world-wide, and are often (but not always) associated with prehistoric peoples. They are one of the three different techniques used in Rock art, the prehistoric precursors to art. The meaning of these works is still unclear, but much conjecture and speculation has been produced in academic circles.

Some petroglyphs seem to depict real events whilst many other examples are apparently entirely abstract. Some theories hold that they may have been a way of transmitting information, while other theories ascribe them a religious or ceremonial purpose. There are many common themes throughout the many different places that the petroglyphs have been found; implying the universality of purpose and similarity of the impulses that might have created the imagery. The phenomenon is thought by many to be the foundation of art as well as an indication of the development of cognitive and abstract ability in the evolution of humankind, as most was created before the advent of the first major civilizations. While we may not understand their purpose, we can appreciate and enjoy the beauty of petroglyphs, admiring the creativity of those from long-ago eras.
