Atures Rapids, near Puerto Ayacucho, Venezuela
Cerro Pintado
Not directly dated (motifs shared with pots of about 100 BC to 1480 CE)
A snake cut into a hill at the Atures Rapids is about 42 metres long. Thirteen sites on the Orinoco carry figures of that monumental class. None of the engravings has a date from the rock, and a Piaroa cosmogony says a travelling woman made pictures like these.
Why this is extraordinary
Where the Orinoco drops through the Atures Rapids, the rock faces carry engravings larger than a house. A 2024 survey mapped rock art along the upper and middle river, 157 locations in the inventory, and classed 13 of them as monumental. Monumental, in that paper, means placed where they dominate the view and at least twice a person’s height, more than 4 metres, in one dimension. The common giant is a snake. The largest, at Cerro Pintado, is more than 40 metres long, and a figure caption estimates about 42 metres from remote-sensing imagery. Humans, animals, and a few geometric signs share the panels. Giant centipedes turn up rarely, and mostly with the snakes. The pin is Puerto Ayacucho, the town at the rapids, because the paper does not print a degree for the hill itself. Some of the thirteen sites stand on the Colombian bank. They are one study. This room’s country is the Venezuelan side, where Cerro Pintado is.
The age is the open half. The engravings are not directly dated. Similar motifs occur on pottery. Around the rapids the excavated sequence has an earlier occupation from 100 BC to AD 620 and a later one from AD 1030 to 1480. Ceramics picked up in rock shelters are the later kind. The authors say there is likely a broad overlap between the settlement and the art, that a formative start around 3000 years ago is possible because people were already visiting, and that an even earlier, preceramic phase, back toward 10,000 years ago in the region, cannot be ruled out and also cannot be shown. A motif on a pot dates a motif. It does not date every snake of that shape, and a shape can be old when it first appears on clay.
Two meanings are set out, and they are not enemies. The rapids were a place travellers had to pass, a corridor of many peoples. A snake tens of metres long, visible from the river and from other hills, is read as a mark of territory and identity, a sign that says someone is here. Views from the savannah are poorer. Hills and stretches of the river see the panels best. The other meaning is cosmological and it is sourced to Piaroa accounts. In that cosmogony a culture hero and an anaconda are opposing powers. Snakes in the wider region are told as bringers of floods and as dangerous creative beings. One woman in the Piaroa telling is said to have made rock art while she travelled the Orinoco in exile. That is a sky-and-river being, not a notch aimed at a sunrise. No azimuth of a snake toward a solstice or a star is published in the paper. You do not observe these engravings by standing in a door at dawn. You observe them by being on the river, small, under a figure that occupies the cliff.
The photograph is a confession of a gap. It shows spirals at Caicara, a different Orinoco site downstream, an older picture of the region’s engraving habit. It is not the 42-metre snake. The monumental panels were recorded by the survey with drones because they do not fit in an ordinary frame. An open photograph of Cerro Pintado itself was not in the set used here.
What this changes: if the snakes are late pre-Columbian road signs, they belong to the centuries of the multi-ethnic towns at the rapids. If they are older, they are a tradition those towns inherited. The Piaroa account can be a memory of that tradition, or a later story laid on pictures that were already mysterious. The paper treats both the territorial reading and the cosmogony as serious, and it says the precise chronology is unresolved.
Why it matters
Scale this large is either a territorial instrument on a river everybody had to use, or a sacred image of a dangerous cosmic snake, or both. The date decides whether the towns of the last millennium built them or inherited them. The cosmogony decides whether “road sign” is too small a phrase.
The size, the rapids, and the anaconda account are the tour. The pin is Puerto Ayacucho, at the rapids. The photograph is Caicara, and it is labelled as a stand-in.

- Cerro Pintado’s snake was recorded from the air because of its size. No open photograph of that panel is used here. The Caicara spirals are a stand-in from another Orinoco site, and the caption says so.
What is still unexplained
These sit beside the consensus account, with the same visual weight. None of them is marked solved.
Location and dating
- Location
- Cerro Pintado at the Atures Rapids of the Orinoco, Amazonas, Venezuela. The pin is Puerto Ayacucho, 5.655 north, 67.600 west, the town at the rapids. The paper does not print a separate degree for the hill. Other monumental panels continue upstream and downstream, including on the Colombian side.
- Period label
- Current consensus — open to revision Not directly dated. Settlement at the rapids runs from 100 BC to AD 620 and from AD 1030 to 1480. A formative overlap from about 3000 years ago is judged possible. A preceramic origin, toward 10,000 years ago in the region, is not ruled out.
- How this dating was done
- Comparison of motifs with dated pottery, and the viewshed of the hills. There is no radiocarbon age on the engravings. The cosmogony is ethnography, recorded accounts of Piaroa belief, not a date.
- What could change it
- A crust over a snake, or an excavation at the foot of Cerro Pintado that ties a buried engraving to a hearth, would replace “likely contemporary.” A published coordinate for the hill would move the pin off the town.
What is actually there
- Thirteen sites are classed as monumental, more than 4 metres in at least one dimension, out of 157 locations.
- The Cerro Pintado snake is more than 40 metres, about 42 metres in one figure estimate.
- Motifs are shared with pottery, but the engravings are not directly dated.
- Piaroa cosmogony includes an anaconda as a primordial power and a travelling woman who made rock art.
- No solstice or star azimuth is published for the panels.
Open questions
| Question | Status |
|---|---|
| Do the giant snakes belong to the last millennium of towns, or to an older visit? | Open. The paper says likely overlap with the dated settlements, and it says earlier production is not ruled out. |
| Are they territorial marks, images of a cosmic snake, or both? | Open. The viewshed supports a mark meant to be seen from the river. The cosmogony supports a dangerous creative being. The paper does not make you choose. |

The current narrative — open to revision
Monumental marks on a river corridor
The giant snakes were made to be seen by people moving through the Atures Rapids, as signs of identity and territory among many groups, most plausibly in the centuries of the excavated settlements.
What supports this
- The rapids are a forced passage, and the viewshed study finds the river and the hills, not the open savannah, are where the panels show.
- The snakes are iconographically consistent across sites, which fits a shared signal rather than private doodles.
- Motifs match pottery of the regional sequence, especially the later occupations.
What pushes back
- The match with pottery is not a date on the rock, and the paper leaves an earlier origin open.
- A purely political reading underplays the cosmogony, in which snakes unleash floods and rock art has a maker in the story.
- Some monumental sites lack snakes, so “the snake as the sign” is the dominant pattern, not a universal one.
What would settle it
It is the paper’s geographical argument, and it is the best account of why the pictures are so large and so placed. It is incomplete without the beings the makers’ descendants describe.
Emerging narratives
Other published readings. Each may be right. None is adopted here unless the evidence carries it.
An emerging narrative
Images of a cosmic anaconda
The monumental snakes depict the dangerous creative serpents of northern South American cosmogony, and Piaroa tradition preserves a memory that rock art on this river was made by a woman travelling in that story.
What supports this
- Recorded Piaroa cosmogony sets an anaconda against a culture hero and credits rock art to a woman travelling the Orinoco.
- Snakes as flood beings are a wider pattern in the region’s accounts, not a single modern remark.
- The size, tens of metres, fits a being rather than a label, if size was the point.
What pushes back
- Ethnography is recent. A story can attach itself to an old picture whose makers meant something else.
- The viewshed and the multi-ethnic corridor still need an explanation, and “sacred” does not replace “placed where travellers look.”
- No astronomical alignment is published, so a cosmic being here is a person in the cosmogony, not a measured star.
What would settle it
It is the Indigenous explanation on the table, and the paper treats it as evidence about meaning. It does not date the engravings, and it should not be asked to.
Should the current view be reevaluated?
Open to revision
The monumental snakes are surveyed, measured in order of size, and placed in a river corridor. Their century is inferred from pottery and left explicitly unresolved. Territory and cosmogony both have published support, and neither cancels the other.
What drives this
- A snake about 42 metres long at Cerro Pintado, one of 13 monumental sites.
- No direct date, and two settlement spans the art may overlap.
- A Piaroa cosmogony of an anaconda and of the making of rock art, with no published solar azimuth.

If the contested reading is right
What would follow if a reading that is not the consensus turned out to be true, and what could settle it. This explains the stakes. It does not adopt the reading.
The snakes are both boundary marks and cosmic beings
People at the Atures Rapids cut the largest rock engravings yet described in order to hold a corridor, and they did it in the shape of a being their cosmogony treats as dangerous and creative.
Why it is still worth a test
A date from a crust or a buried panel at Cerro Pintado, and a coordinate that lets the pin sit on the hill.
