Cerro Guasú, Amambay, and related hills, Paraguay
Amambay rock art
Mid-Holocene hearth date (5,212 ± 323 before present, on one fire)
Three sandstone shelters on Cerro Guasú, the hill the Paĩ Tavyterã call Jasuka Venda, are cut with more than a thousand tracks and signs apiece on the two large walls. A hearth under one of them has a published thermoluminescence age of 5,212 ± 323 before present. Books from 1972, 1975, and 1979 read marks in these hills as Norse runes.
Why this is extraordinary
Cerro Guasú is a sandstone hill in the department of Amambay, 60 kilometres from Pedro Juan Caballero. A 2015 conference paper measures it at 11 kilometres across, 350 metres at the base and 710 at the summit. Along one outcrop, three rock shelters stand about 500 metres apart. The Paĩ Tavyterã, a Guaraní people whose traditional land includes this hill and the Brazilian border beside it, call the hill Jasuka Venda. In their account it is the centre of the world. One of the shelters has been taken into that account as the house of Ñande Ru, the creator and father.
The walls are cut almost solid. A petroglyph, here, means a mark pecked, scraped, or incised into rock. At the shelter called Itaguy Guasu the 2013 excavation report inventories 1,385 graphic units: animal tracks, human footprints, a smaller group of vulva-shaped signs, and abstract pits, cupules, and lines. Itaguy Mirî, the next large shelter, has 1,674 units in a partial count, and the paper says several hundred more are there. The grooves are wide. The report's average is about a centimetre across and half a centimetre deep, which is easy in this sandstone and still deep enough to read after the visor of one shelter collapsed.
In 2008 a pit of 2 square metres, dug to bedrock at 70 centimetres beside the engraved wall of Itaguy Guasu, found one sandy occupation and one hearth. Thermoluminescence, a clock that reads when mineral grains were last heated, dates reddened sandstone from the base of that hearth to 5,212 ± 323 before present. The same digits are printed as years BC on Paraguay's 2022 tentative list. Those are not the same calendar claim. The report assigns the engravings to that occupation because the pit has one level and the wall has one repertoire. It also says the date cannot yet be called the start, the middle, or the end of the cutting.
A different reading has been in print since the 1970s. Jacques de Mahieu, through the Institute of the Science of Man in Buenos Aires, published the marks as pre-Columbian runic inscriptions, in 1972 and again in a 1975 supplement on Cerro Guazú. A 2023 account in La Nación, drawing on his writing, reports a 1973 note of 61 characters at Cerro Guazú already translated, expeditions from 1975 to 1979, a white king named Ipir, a fortress wall inside Cerro Corá National Park, and a dressed-stone foundation at Tacuatí carrying a sign he read as the rune gebo. The same account says he wrote at least half a dozen books on Viking voyages from the far north of the Americas to this border. The northern camp with a calendar year is L'Anse aux Meadows. Stones farther south that have been read as runes are in Runestones in America. Neither of those catalogues is a wall in Amambay.
What this changed
The shift, in short. The weighing further down is the longer argument.
- Older textbook view
- The walls entered public notice in 1973 as aboriginal shelters of about 2500 to 3500 BC, and in the same decade as Norse runes. The footprints repertoire, named in Patagonia in 1957, was being placed later than this hearth in Argentina and Brazil.
- New evidence
- One thermoluminescence age on reddened hearth sandstone, one lithic level in a 2-square-metre pit, and inventories of 1,385 and 1,674 graphic units on the two large Cerro Guasú walls.
- How it is dated
- Thermoluminescence of heated sandstone, printed as 5,212 ± 323 before present in the 2013 report and as 5,212 ± 323 BC on the 2022 tentative list. The grooves themselves were not dated.
- What moved
- A middle-Holocene occupation is now published for Itaguy Guasu, and the marks are catalogued with the footprints repertoire. The year of each groove is still an assignment, not a measurement on the cut.
- What is still disputed
- The unit BC against before present, a Guaraní sherd date that the 2013 article does not print, and the rune books, which remain a separate reading of the same hills.
Why it matters
If the hearth age belongs to the cutting, track-and-sign engraving was already a crowded practice in eastern Paraguay in the middle Holocene, earlier than the dates usually given to the same repertoire in Argentina and Brazil. If the tentative list's printing of those digits as BC is the right unit, the fire is older still. If de Mahieu's translations are the carver's text, Norse writing reached the Paraná–Paraguay divide, and a mid-Holocene hearth is a fire in a shelter that was marked again, or marked for another reason. The Paĩ reading, that the hill is where the world was begun and that the marks are ancestral messages, is a third claim, about meaning, and it does not have to lose for either clock to be kept.
A shelter here is a shallow cave under a lip of rock, open to the weather along a drip line. A cupule is a round hollow. The report calls anything under 2 centimetres a point, and anything wider a cupule. A tridigit is three strokes meeting at a point, read as the track of a rhea, the ñandú. Paired short strokes are read as deer, and a central pit with smaller pits around it as a jaguar. Guasu, in Guaraní, means large, and it is also the name the Paĩ use for the deer. Mirî means small. The conference paper says the leaders used those names to mark the shelter they held in higher regard, and it also calls Itaguy Mirî the larger shelter. The floors printed in the same paper are 265 square metres and 196.

Location and dating
- Location
- The pin is 23° 05' S, 55° 59' W, the degrees and minutes of the single position the tentative list prints for Itaguy Guasu, Itaguy Mirî, and Itaguy'i. The seconds on that line are not a readable figure, so they are not in the pin. The conference paper's 60 kilometres from Pedro Juan Caballero is the other location it gives for the hill. Itaguy Guasu is the excavated shelter, at 465 metres. Akua 1, the hill in several of the photographs, is the list's 22° 40' 16.8" S, 56° 09' 29.5" W. Cerro Polilla and Ita Letra are in Guairá, in the Yvytyrusú reserve, not on this pin. Cerro Corá National Park holds Tujao and Alambique. Stones read as runes in North America are in Runestones in America. The dated Norse camp is L'Anse aux Meadows.
- Period label
- Current consensus — open to revision The excavation report's age for the Itaguy Guasu hearth is 5,212 ± 323 before present, middle Holocene, and the engravings are assigned to that occupation. The tentative list prints 5,212 ± 323 BC for the hearth and 734 ± 67 BC for a Guaraní sherd, and it associates the footprints repertoire with 3500 to 1800 BC, with later Guaraní and Jê pottery at the sites. The 1973 newspaper figure, quoted in the report, was 2500 to 3500 BC. The rune books place makers from the Norse world in these hills in the 1970s argument, without a laboratory year in the sources used here. Current consensus, open to revision. The marks are Indigenous petroglyphs of the footprints repertoire. The year of any one groove is not measured.
- How this dating was done
- Thermoluminescence on reddened sandstone from the base of a hearth. That dates a heating, not a groove. The link from the fire to the wall is the single level in the pit and the single repertoire on the stone, which is a use of stratigraphy. Comparing these signs with the Patagonian and Brazilian series is a kind of typology. Bone and charcoal were taken. No radiocarbon age for them is in the 2013 article. No archaeoastronomy of these shelters is in the sources used here.
- What could change it
- A second laboratory report on MAD-5468BIN that states whether 5,212 ± 323 is before present or BC, and a date on a sample from a named groove, or from a crust that formed inside one. A published reading of the 61 characters, sign by sign, that another epigrapher can repeat. For the Paĩ account, the oral identifications set beside the panels, which the 2008 season began and did not finish as a translation.
What is actually there
- Cerro Guasú is 11 kilometres across, 350 to 710 metres, 60 kilometres from Pedro Juan Caballero.
- Three shelters share one outcrop, about 500 metres apart.
- Itaguy Guasu has 1,385 inventoried units. Itaguy Mirî has 1,674 in a partial count. Itaguy'i has 197.
- The 2008 pit was 2 square metres, to bedrock at 70 centimetres, with one occupation.
- The published hearth age is thermoluminescence, 5,212 ± 323 before present, sample MAD-5468BIN.
- The tentative list prints those digits as BC, and adds a sherd at 734 ± 67 BC.
- The lithic count is 6,811 pieces and 55 tools in the article, and 6,378 flakes and 55 tools on the list.
- De Mahieu's 1972 and 1975 books read the marks as runes. La Nación reports 61 translated characters at Cerro Guazú.
- Itaguy Mirî carries the modern words Cerro Guasu and Delio, and two unpatinated horses with a fine-line human figure.
- Cerro Polilla is inventoried with Ita Letra in Guairá, not as an Amambay summit.
- Jasuka Venda is Paĩ heritage by decree 7,685 of 1990 and resolution 21 of 2005.
Open questions
| Question | Status |
|---|---|
| Does 5,212 ± 323 date the cutting, or only the fire? | Open. The report assigns the wall to the occupation and says the date may be early, middle, or late in the life of the marks. |
| Is the published unit before present, or BC? | Open. The excavation report and the tentative list print the same digits with different units. |
| Are any of the marks the 61 characters translated in 1973? | Open. The newspaper reports the translation. The inventory reads the walls as tracks and abstract signs, and it separates a few unpatinated animals as modern. |
| What do the Paĩ oral readings say about the signs that are not tracks? | Open. Jaguar, rhea, and deer were named in the shelter. A full account of the other signs is not in the papers used here. |

The current narrative — open to revision
Indigenous tracks and signs
The walls are petroglyphs in the footprints repertoire, cut by people who also left planoconvex tools and bifacial points in the shelters. The Itaguy Guasu hearth dates a middle-Holocene occupation, and the engravings are assigned to it because the pit has one level and the walls have one style. Later Guaraní use of the hills is a separate chapter, not a Norse one. Cerro Polilla and Ita Letra belong to the same repertoire in Guairá.
What supports this
- The inventories sort the marks as jaguar, deer, rhea, human feet, vulvas, and abstract signs, the set named in Patagonia in 1957 and since found across Argentina and Brazil.
- Paĩ observers in the shelter used the same animal names for the same shapes.
- One occupation, 6,811 pieces of flaked stone, and a hearth at 5,212 ± 323 before present sit against the engraved wall.
- Grooves average about a centimetre wide in soft sandstone, which is the technique the tentative list describes for the whole series.
- The 2015 paper separates two horses and a fine-line figure at Itaguy Mirî as modern, by the lack of patina, and reads the older wall as the same repertoire as the other shelters.
- The journal records that the 1970s rune books had no credit outside Paraguay and were rejected in print in 1984, after which the photographs were described as footprints engraving.
What pushes back
- The hearth dates a fire. The report itself will not say whether that fire is early, middle, or late in the cutting.
- The tentative list prints the hearth as BC and adds a Guaraní sherd at 734 ± 67 BC, so the single-level story in the 2013 article is not the only published occupation.
- Tool types often placed in the early Archaic and a repertoire often placed later are being asked to share one century.
- De Mahieu published translations, a gebo sign at Tacuatí, and a fortress reading of the Cerro Corá wall. An inventory that does not reprint those 61 characters has not yet answered them sign by sign.
- Abstract signs and radial grooves can be read as writing by a viewer who brings a rune row. The tracks do not exhaust the wall.
What would settle it
A groove-by-groove publication of the 61 translated characters, set on a photograph, would show whether they are a selection of the tracks and lines already counted or a text the inventory did not see. A second sheet for MAD-5468BIN would settle the unit. Until then the repertoire and the lithics are the best-supported reading of the walls, and the year of each mark stays assigned.
Emerging narratives
Other published readings. Each may be right. None is adopted here unless the evidence carries it.
An emerging narrative
Norse runes from a southern voyage
Jacques de Mahieu's reading is that some of these cuts are Norse runes, left by Vikings in South America. The 1972 and 1975 books present the Amambay and Yvytyrusú marks as pre-Columbian runic inscriptions. The 1979 book, as a 2023 account of it reports, carries the expeditions, a translated set of 61 characters at Cerro Guazú, the white king Ipir, a fortress in Cerro Corá, and a stone temple at Tacuatí with a gebo rune. The wider theory is a Norse journey from the far north of the Americas to this border, told across several of his books.
What supports this
- The marks exist, in deep grooves, and a portion of them are abstract signs, radial forms, and lines that a reader can compare with a rune row.
- La Nación reports a 1973 record of 61 characters at Cerro Guazú, already translated, and quotes his identification of a gebo sign on a dressed block at Tacuatí.
- The same account gives his case that the Cerro Corá wall keeps geometric edges a geologist did not treat as ordinary breakage, and that the Tacuatí foundation is dressed stone without mortar under a later church.
- An oral story of a white, bearded king named Ipir was collected in the hills before his expeditions, in the newspaper's telling, from elders through Fritz Berger.
- A Norse camp at L'Anse aux Meadows shows that a voyage west from Greenland happened. His books ask how much farther such a voyage could be taken.
- Two profile horses at Itaguy Mirî are real cuts. A horse is part of the case he made for Old World animals on the walls.
What pushes back
- The 2013 inventory of the same hills reads the mass of the walls as tracks and signs of a repertoire already defined in 1957, not as a rune row.
- The only published laboratory age is a middle-Holocene hearth, millennia before the Norse centuries, unless the tentative list's BC printing is used and even then the fire is far older than a medieval voyage. The age is the fire, not a proof that no one cut a mark later.
- The conference paper treats the horses and the fine-line human figure as modern, because they have no patina, and it records modern names cut over the old grooves.
- The journal states that the rune books had no credit outside Paraguay and that the speculation was rejected in 1984.
- L'Anse aux Meadows has buildings and iron and, in the published find lists, no rune. A camp there does not identify a letter in Amambay.
- No second epigrapher's repetition of the 61 translations is in the sources used here. A translated set that cannot be checked sign by sign is a claim about a text, not yet a text on the page.
What would settle it
The rune reading stands or falls on a published comparison, character by character, with the walls as they are inventoried, and on a date for a mark he translated rather than for the hearth alone. The fortress and the Tacuatí foundation need the same treatment, a plan and a context another crew can dig. The northern camp stays evidence that Norse ships crossed an ocean. It does not, by itself, label these grooves.
An emerging narrative
Ancestral messages on a creation hill
For the Paĩ Tavyterã, Jasuka Venda is the centre of the world, the place where Ñande Ru began it, and one shelter is his house. The petroglyphs are messages left by their ancestors. The tracks of jaguar, rhea, and deer are the animals they named in the shelter, and the hills remain theirs to keep.
What supports this
- Decree 7,685 of 1990 and resolution 21 of 2005 recognize the hill as Paĩ heritage, and the land is held by Paĩ Retã Joaju.
- The tentative list states their account in those terms, ancestors and creation, and calls the sites a living heritage.
- The conference paper records that one shelter entered the oral story as the creator's house.
- In the shelter, tekoaruvicha identified jaguar, ñandú, and deer, matching the shapes the inventory counts.
- The finds were returned to the association and later placed in the Andrés Barbero museum, which is the list's account of who holds the material.
What pushes back
- An account of meaning does not, by itself, choose between a middle-Holocene fire and a later hand.
- The papers used here do not print a Paĩ reading of the abstract signs, the vulvas, or the six human figures, so most of the wall is still untranslated on their terms.
- De Mahieu's Ipir story is also an oral account from the hills, about a white king rather than about Ñande Ru. Two oral accounts can be collected in one region and still not be the same story.
- The Guairá sites, Cerro Polilla and Ita Letra, are in the same repertoire and are not described as Jasuka Venda.
What would settle it
A recording of the oral readings, panel by panel, published with the inventory numbers, would show which signs the creation account actually uses. The heritage decrees already settle whose hill it is. They do not settle the century of a groove.
Should the current view be reevaluated?
Open to revision
The footprints inventory is the best-supported reading of what is cut, because the walls have been counted, the shapes match a repertoire published across the southern continent, and the Paĩ names for the animals agree with that sorting. The hearth age is a real laboratory result and it is not a date on a groove. The same digits printed as BC, the sherd the list adds, and the tool counts that do not match are enough to keep the year open. De Mahieu's translations, the gebo block, and the fortress are a published reading with named places, and they have not been answered by a sign-by-sign reply in the sources used here. The room stays open on the year and on the meaning. It does not have a second Norse archaeology, of the Newfoundland kind, in these shelters.
What drives this
- 1,385 units at Itaguy Guasu and 1,674 at Itaguy Mirî, mostly tracks, pits, and lines.
- A 2-square-metre pit with one occupation, planoconvex tools, and hearth sample MAD-5468BIN at 5,212 ± 323 before present.
- The same digits printed as BC on the tentative list, with a Guaraní sherd at 734 ± 67 BC.
- De Mahieu's 1972 and 1975 books, the 61 characters reported from 1973, and the 1979 Hachette volume.
- Unpatinated horses and modern names at Itaguy Mirî, separated by the 2015 paper from the older wall.
- Jasuka Venda as a Paĩ creation hill, recognized in 1990 and 2005, with one shelter told as the creator's house.

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 translated marks are Norse runes, and the hills held a Viking refuge
Norse travel would not stop at a Newfoundland terrace around 1021. Writing, a fortress, and a stone temple would stand on the divide between the Paraguay and the Paraná, and the oral king Ipir would be a candidate for a historical person. The middle-Holocene hearth would be an earlier fire in a shelter that was inscribed again. The footprints counts would have to be re-read as a code, or as a mixture of an old repertoire and a later text.
Why it is still worth a test
The 61 characters published against photographs of the panels, and a date on one mark included in that translation. A plan of the Cerro Corá wall and of the Tacuatí foundation, with the gebo block identified.
The walls are ancestral messages, and the hill is where the world began
The shelters would be a sacred text still in use, not only an Archaic picture gallery. A motif catalogue would remain a description of shapes and would not be a translation. Protection of the kind the Amambay sites already have, from the people who live with them, would be part of the record, which is how the tentative list already distinguishes them from Ita Letra.
Why it is still worth a test
The oral account written down beside the panel numbers, including the signs that are not animals. The decrees already say whose hill it is.
