More than 2,000 years ago, the Tukano people of the Colombian Amazon may have documented the soundtracks to their hallucinogenic experiences in petroglyphs on volcanic boulders. Consisting of what appears to be dancing human figures surrounded by zigzagging lines and other geometric forms, the enigmatic art eludes concrete interpretation, although a new analysis suggests that these abstract shapes may depict the songs that transported participants to other dimensions during Ayahuasca ceremonies. The pre-Columbian designs can be found at Toro Muerto, which contains one of the richest collections of rock art in South America. A desert gorge, the site is strewn with thousands of boulders, some 2,600 of which feature ancient carvings.
Describing the drawings in a new study published in the Cambridge Archaeological Journal, researchers explain that the artworks contain "an almost overwhelming repetition of images of dancing human figures (known as danzantes), unique in the region, and an extraordinary accumulation of geometric patterns, most often in the form of vertical zigzag, straight and sinuous lines varying in width, sometimes with accompanying dots or circles." Previous attempts to interpret these zigzags have suggested that they may represent snakes, lightning, or water, although the study authors believe they may have an alternative meaning.

To build their hypothesis, the researchers point out the striking similarities between the drawings at Toro Muerto and the traditional artwork of the Tukano culture in the Colombian Amazon. In the case of the latter, geometric designs have been linked to the visions induced by the hallucinogenic brew Ayahuasca, which has been ritually ingested by Indigenous Amazonian communities for millennia. According to the Tukano these drawings were 'yajé images', meaning that they showed patterns they had seen while in an altered state of consciousness induced by consuming entheogens. Concentric circles, dots, wavy lines, zigzags and crenellation motifs dominated among them.
Anthropological analyses of these rituals have repeatedly highlighted the importance of music, with songs known as icaros being sung by shamans as a means of communicating with the gods and journeying through the spiritual cosmos. Ritual in many human cultures involves music; it is a key social technology for building and sustaining community. Ritual music is a universal way to address the spirit world and provide some kind of fundamental change in an individual's consciousness or in the ambience of a gathering. Experiences of ego loss and trance are important for integrating the individual into the group and maintaining community, and music is a significant element of such ritual activity.
Intriguingly, studies into the significance of zigzags in Tukano artwork have revealed that "the Tukano saw in them the representations of songs which were an integral part of the ritual, having also agentive power, and constituting a medium for transfer to the mythical time of the beginning." In other words, within a Tukano context, these shapes depict the shamanic music that mesmerizes ritual participants under the effects of Ayahuasca, delivering them to an alternate reality in which they are able to reconnect to their ancestral mythology.
Admitting that their theory is somewhat speculative, the researchers nonetheless conclude that these pre-Hispanic drawings "illustrated a graphically elusive sphere of culture: singing and songs. The interpretation we propose is of course hypothetical, but the conclusions it leads to constitute a logically coherent counter-proposal to previous interpretations of some of the Toro Muerto petroglyphs. We suggest that zigzag lines could be representations of songs, which seems particularly intriguing given the repeated juxtaposition of these patterns with the figures of dancers at Toro Muerto."
