The Wonderful World of ROCK ART

This month, we are delving into the fascinating world of rock art. There are many kinds of rock art but they are all human-made and found on natural surfaces. Different types of rock art can be found all over the world and have been found on every continent, except for Antarctica. In archaeology, rock art is important to study because it can give deeper insight into the cultures that created them. Some of the more well-known types of rock art are pictographs, petroglyphs, and petroforms.

Pictographs

Cave of Altamira and Paleolithic Cave Art of Northern Spain

A pictograph is similar to a painting and is made by mixing minerals and wet substances like animal fat, oil or blood. The most commonly used colors are black, red, and white. Red paint is made from ground ochre, black paint is usually composed of charcoal, and white paint comes from clay or natural chalk. Animals and tools are commonly found images as well as handprints.

Petroglyphs

This petroglyph photograph was taken by Alan Levine and is located in Winslow, AZ.

Petroglyphs, unlike pictographs, are engravings that are carved into rock. Tools like a hammerstone or sharpened rock would be used to remove unwanted stone and create the desired shapes and symbols. There are many different techniques for creating a petroglyph.

Petroforms

Petroforms are human-made shapes or patterns placed on open ground using large rocks. These are generally much larger than petroglyphs and pictographs and are thought to have many purposes. The placement of these rocks could represent burial or ritual sites, or perhaps have aided in navigation. Much is still unknown about rock art as it many times is highly symbolic.

Preserving Rock Art

Rock art, like other cultural heritage, need your protection. If you visit a rock art site, do not touch, paint, or climb upon the art. Protecting the past is important and these sites are precious.
