Southern Peru is home to one of the richest sites with rock art in South America—Toro Muerto. A unique aspect of the iconography of the petroglyphs of the site is the figures of dancing humans, the so-called danzantes, which are additionally frequently associated with geometric motifs, mostly variants of zigzag lines. Drawing upon intriguing data recorded during Reichel-Dolmatoff's research in Colombia related to the meaning of analogous motifs in Tukano art, as well as broader exploration of the sonic sphere in South American cultures and the thesis that Amazonian animism was a more archaic ontology over a broader area of South America, this paper suggests that the geometric patterns at Toro Muerto, with which the figures of danzantes are juxtaposed, may have been representations of songs. An extension of this hypothesis is the suggestion that some of the more complex compositions consisting of danzantes and linear geometric motifs were graphic metaphors of transfer to the other world.
