Work done by others is always fascinating, which is why national parks featuring ancient ruins are so popular; they showcase the incredible and often very beautiful work done in the Southwest before Europeans arrived.
It takes a lot of work and skill to create a petroglyph. I know, I've tried it. A full day's work produces only a small image. First, find a hard river stone with a pointy end; then, spend hours using it to chip away enough desert varnish and surface rock to make a shallow indent on a large boulder or cliff face. When you finish, since rocks don't rot or grow back, the design will last thousands of years.
Rock art wasn't doodles or graffiti, churned out in a trivial moment or so; it is serious statements of faith that Native Americans took days or weeks to produce. The original meanings may never be recovered, which is a great loss; but, the artistry can still be appreciated. Patterson's sketches are clear, concise and free of unrelated static. Since petroglyphs are the originals of modern Native American art, this is also a guide for artists, historians and poets of the Southwest.
It is a bilingual dictionary, everything from "arrow" and "atlatl" to "X-ray styles." In Spanish, it helps to know "Alto" means "Stop;" in the petroglyph language, it helps to know what sign means "Sun." Patterson offers educated insights into 600 common petroglyphs. People today link certain symbols to ideas, such as an "apple" as a gift for a teacher, a still life art object, a kind of pie, or a computer. In all likelihood, every petroglyph had as many or more meanings -- depending on the story teller.
Consider Patterson's description of the sun sign, which is still a popular design for silver jewelry from the Pueblos: ". . . the outer circle represents the ring of light around the Sun, the second represents the sun itself, and the inner circle or dot, his umbilicus, which opens to provide mankind with game and other sustenance." Next, think of modern artists who see the sun and paint a yellow circle, while others paint a yellow circle and create a sun. Now, the petroglyph sun sign takes on new meaning.
Art expresses a sense of adventure. A thousand years ago, petroglyphs were patiently chipped into boulders and cliffs to create a permanent memory of unique and special events. They portray a dramatic history of gods, demons, giants, tricksters and rare events as powerful and devious and clever as any Nordic saga. They also offer maps to the beginning of creation and pathways to a fulfilled life. Petroglyphs are a record of the exploration, knowledge and interpretation of America long before its "discovery" by Europeans. It reminds us that we have much yet to understand; it may not be the "Rosetta stone" of the Southwest, but it is one of the texts.
This is a masterful guide, sensibly devoid of guesswork and idle speculation (that's my field). Every society invents, discovers, experiments and creates to explain its origins and values. Patterson classifies common themes that were important enough to be written on rock. Rock art is one of our cultural treasures. If you want a book of facts about it, this is where to start.
