Rock art, a Cultural Phenomenon

The generic term rock art refers to a very ancient form of visual expression. This form of art includes painted, drawn and carved works found on rock formations of every kind: caves, rock shelters and open-air erratic boulders or rock outcrops. The expression cave art is used to identify art in enclosed spaces, including grottoes and caves. Found on the five continents, rock art sites are among the most widespread cultural phenomena of humanity. They have stood the test of time and many can be seen to this day.

In North America, researchers often use the term pictograph to identify painted and drawn works, while carvings are called petroglyphs.

Researchers also include other types of work under the term rock art: (a) Lichenoglyphs are created by scratching the surface of a rock covered in lichen to create, by contrast, a more or less complex motif; (b) Sgraffiti are motifs produced on the surface of a rock by removing the top layer to reveal the contrasting layer underneath. These motifs are typically in lighter hues, as the rock surface acquires a darker patina over time; (c) Petroforms are rocks laid out in lines or circles on the ground, or piled on top of each other – such as an Inuit inukshuk – to form a figure. Petroforms have several purposes: practical or related to the cosmology of the groups who created them; (d) Geoglyphs are large-sized geometric or figurative motifs created by removing the surface of the ground to produce a contrasting motif with the layer underneath. Naturally, these motifs are best appreciated from afar, especially from above, like the Nazca Lines in Peru or the giant horses shaped in chalky ground in southwestern England.

Art, Signs or Symbols

Archaeologists have combined the words art and rock to highlight the fact that rock art is a deliberate form of visual expression which reveals a practice of creation not unlike any artistic process (design, search for appropriate materials like painting pigments, use of appropriate tools, identification of surfaces to decorate, etc.). However, in most cases, rock art sites were not created for purely aesthetic purposes, even though some of them may be considered as genuine works of art. With regard to the graphic content of these images, rock art has a vast array of signs and symbols, from the simplest to the most complex motifs. Therefore, certain compositions appear quite rudimentary with a few sparse motifs, while others are utterly complex works of art featuring a plurality of figures of all kinds.

History of Scientific Discoveries

It was in the 20th century, more particularly since the 1950s, that genuine interest in rock art study started thanks to the work of Selwyn Dewdney (1909-1979), an artist and researcher affiliated with the Royal Ontario Museum in Toronto. Today, Dewdney is considered to be the father of rock art research in Canada. He spent more than 20 years exploring a vast territory stretching from Alberta to Quebec, revealing the existence of some 300 rock art sites. Dewdney sometimes travelled in the company of Indigenous informants. Famous late artist Norval Morrisseau travelled with him on several occasions. Over the last sixty years, avid researchers from practically all the Canadian provinces have contributed to advancing research on rock art.

Rock Art Typology

No matter where they are found in the world, rock art drawings, paintings and carvings feature a wide variety of motifs. Analysis allows for the identification of different types of representations and their regional categorization. Hence, there are two main categories of motifs, regardless of the means of representation chosen: geometric and figurative motifs. Rock art sites feature a wide range of geometric motifs, from the simplest tracings (dots, lines, curves) to more complex (lattices, arabesques) or intermediate ones (circles, triangles, squares or rectangles, zigzags, spirals, etc.). What do these motifs represent? Without appropriate knowledge of the rock art producing culture and its codes, it is practically impossible to associate with certainty any significance to these motifs: they are abstract and their link to a figurative form is often hard to establish.

Figurative motifs, however, include several types of representations likely to be recognized by their form, whether schematic or natural. Hence, there are human-like figures (known as anthropomorphs), animal figures (also known as zoomorphs) and figures resembling plants (called phytomorphs). These motifs also include representations of material culture (canoes, clothing, bow and arrows, etc.) and natural environment (rock formation, waterway, sun, moon, stars), as well as figures with hybrid features (i.e. combining human, animal and plant features). Sometimes, artists represented beings in a combination of animal and / or human features indicative of powerful characters, such as Underwater beings. Hands and feet were also represented as imprints or stencils. Figurative images can typically be identified, although their subject matter may remain elusive. However, despite their identifiable appearance, all these figures may bear a yet unknown significance.

On a last note, the identification of these two major image categories, figurative and geometric, is the result of modern Western scientific research. The artists who created these images did not necessarily make such distinctions.
