Comparison of sea urchin with Chumash rock art figure. Ever since reading Guthrie’s “The Nature of Paleolithic Art,” an ecological explanation of rock art forms is, for me, never too far from the visionary or shamanic—nor must the two be mutually exclusive. Foraging societies are steeped in natural history (and corresponding myths of “when the animals were people”). I know the Chumash spent much of their 13,000 year-long history eating a diet dominated by shellfish, urchins included, and that, ala Levi-Strauss, “what’s good to eat is good to think.” Note the circle within a circle in the figure’s chest, which resembles the “nested” appearance of the sea urchin’s mouth, as do the figure’s expanding “arms” and “legs” with the urchin’s shell pattern. Finally, consider the Chumash’s association of the sun with the sand dollar and its patterns. Their art, like their thinking, was probably homologous.
[UPDATE: Archaeologist Al Knight has since directed me to Hoskinson’s 1983 article “Sand Dollars, Sea Urchins, and Chumash Rock Art.” So there is a connection.]
