One of the Ica stones, featuring depictions of various different dinosaurs

The Ica stones are a collection of andesite stones from the Ica Province in Peru, known for their engraved motifs. Largely regarded to be modern hoaxes,[1][2][3] the stones in some cases utilize art styles from various pre-Columbian Peruvian civilizations and often depict anachronistic scenes or objects, including dinosaurs and advanced technology.

Although first popularized in the 1960s and 1970s, stones with engraved artwork were first reported in Peru in the middle fifteenth century during the Spanish conquest. Subsequent archaeological finds have been next to non-existent, though huaqueros (grave robbers) at some point prior to the 1960s began selling stones similar to the Ica stones. The most widely known collection of stones, numbering around 20,000 individual objects, belonged to the physician Javier Cabrera Darquea, who purchased the majority of them from the farmer Basilo Uschuya and believed them to represent evidence of an ancient interstellar civilization that once existed in Peru for hundreds of millions of years.[4] Uschuya later admitted to having forged the stones he sold to Cabrera.[1]

Since the stones have never been able to be examined in an archaeological context[2] and no other expected evidence exists of the advanced civilization supposedly depicted on them,[1] it is unlikely that such a society existed. The dinosaurs depicted on the stones reflect outdated ideas of dinosaur life appearance common in the 1960s[5][6] and depict groups not known to have lived in South America,[7] making it unlikely that they are depictions made by people who actually saw living dinosaurs. Despite by and large being seen as hoaxes, the Ica stones are popular pieces of "evidence" among certain pseudoscientific communities, such as Young Earth creationists and ancient astronaut proponents.[1] It is possible that some of the Ica stones are genuine pre-Columbian artifacts,[1][4][5] though this possibility is mainly maintained for stones not part of Cabrera's collection and with more conventional depictions of humans and animal life.[4]

Description

The Ica stones have all been reported from the Ica Province in Peru. The Ica stones are composed of grey andesite,[5] a type of volcanic rock. They vary considerably in size, from very small (a few centimetres across) to boulders over half a metre across.[5][6]

All of the stones possess a dark patina on which the various motifs are engraved,[4] scratched through the oxidized surface.[5] Supposedly as a result of weathering, the patina is relatively thin, consisting of a weathering rind in which weathering has turned some of the feldspar into clay, resulting in a softer material, rated 3 to 4 on the Mohs scale of mineral hardness, soft enough to be scratched.[8]

History

Background

Archaeological discoveries show evidence of Peruvian cultures going back for several thousand years. At some later stages, the whole of modern Peru was united into a single political and cultural unit, culminating in the Inca Empire, followed by the Spanish conquest. At other stages, areas such as the Ica Valley, a habitable region separated from others by desert, developed distinctive cultures of their own.[9]

Engraved stones have been known from the region since long before the Ica stones were reported. The earliest known reports of similar artifacts are records by the Jesuit missionary Padre Simón, who travelled Peru during the Spanish conquest of the Inca Empire in the early and middle fifteenth century.[4][5][6] Examples of these stones were reportedly sent back to Spain in 1562.[5]

Early archaeological excavations in the Ica Province in the late nineteenth and early twentieth century by scholars such as Max Uhle, Julio C. Tello, Alfred Kroeber, William Duncan Strong and John Howland Rowe did not result in any reports of the finding of engraved andesite stones.[8] Nevertheless, engraved stones which had been looted by huaqueros, grave robbers, at some point began to be offered for sale to tourists and amateur collectors.[8]

An extraordinary[10] amount of Ica stones are known today, with the total number estimated to be around 50,000[2][4]–100,000.[7]

Cabrera's collection

The most widely known collection of Ica stones is that of the physician Javier Cabrera Darquea (1924–2001).[6] According to Cabrera's own account, his interest in the stones was first triggered on 13 May 1966, when he was given one of the engraved stones as a birthday present by his friend Felix Llosa Romero.[4] Possessing a keen interest in Peruvian prehistory,[4] Cabrera identified the motif of the stone as a type of prehistoric fish.[4][6] Cabrera never explained what particular fish species he believed the stone to depict or why he thought it was a prehistoric one.[1][5][11]

In order to expand his collection Cabrera reached out to the brothers Carlos and Pablo Soldi, collectors of pre-Inca Peruvian artifacts. The Soldis reportedly had a large collection of similar engraved stones, according to them found in the Ocucaje region, and sold 341 of them to Cabrera.[4] The Soldis claimed to have begun collecting the engraved stones in 1961, when a large number of them were supposedly uncovered through a flood of the Ica River.[4]

Further stones were acquired by Cabrera through being purchased from the farmer Basilo Uschuya, who provided him with many thousands of them.[4][6] In addition to his own set of acquired stones, Cabrera also kept a collection of similar stones supposedly found by his father, Bolivia Cabrera, at their plantation in the 1930s.[4][6] By the late 1970s, Cabrera's collection contained over 11,000 engraved stones.[4] While serving as a medical professional (including a tenure as the chief of the University of Lima's Department of Medicine) Cabrera initially kept his collection and interest a secret.[6] By 1970 the stones and Cabrera's ideas concerning them were however becoming well-known.[4]

Further stones from Cabrera's collection

In 1996, Cabrera stopped practicing medicine and opened a museum,[6] the Museo de Piedras Grabadas ("Museum of Engraved Stones"),[5][12] to showcase his collection.[6] The museum is organized by the subject of the motif and the stones are lined up along the walls.[4] Cabrera referred to the stones as "gliptoliths" and put forth his own hypothesis on their origins, published in his book The Message of the Engraved Stones of Ica.[12] According to Cabrera, the stones were made by an ancient type of human which he called "Gliptolithic Man", who had larger brains than modern humans and could use their psychic energy to influence events in outer space. Gliptolithic Man supposedly appeared on Earth at least 405 million years ago and left the planet before the Cretaceous–Paleogene extinction event 66 million years ago to travel to a planet among the Pleiades. Cabrera suggested that they left onboard electromagnetic spacecraft from the area that includes the Nazca Lines, which he thought was an "ancient spaceport".[4] Due to a lack of evidence, Cabrera's interpretation has found little acceptance even among pseudohistorians.[4] By the end of his life, Cabrera's collection reportedly contained around 20,000 stones,[5] many of which remain exhibited at his museum.[7] The National Chamber of Tourism of Peru lists the museum as a tourist destination.[1]

Calvo's collection

Ica stones were also collected by the architect Santiago Agurto Calvo,[6][8] rector of the National University of Engineering in Lima.[8] In addition to reportedly purchasing many such stones from locals,[6] Calvo organized searches in ancient cemeteries and in August 1966 reported the finding of an engraved stone in the Toma Luz sector, Callango district, in Ica Valley. The context of the find reportedly corresponded to the Tiwanaku culture.[8] Calvo believed that the engraved stones were part of some ancient burial ritual.[6]

Calvo reported his discovery to the Regional Museum of Ica, and was accompanied on further expeditions by its curator, the archaeologist Alejandro Pezzia Assereto.[8] In September 1966 in Uhle Hill cemetery, De la Banda sector, Ocucaje District, they reportedly found an engraved stone in a tomb of the Paracas culture. On the small stone, a few centimetres across, was engraved a design which might be abstract, or could be taken as a flower with eight petals.[8] Calvo published the discovery in a Lima newspaper.[13] Pezzia continued to search. In the San Evaristo cemetery in Toma Luz, he reported the find of an engraved stone of similar size to the previous one, depicting a fish. The context reportedly dated the tomb to the Middle Horizon (c. 600–1000 A.D.). In a nearby grave in the same cemetery, Pezzia reported the find of a stone depicting a llama. Pezzia published his findings in 1968, including drawings and descriptions.[8]

In 1968, Calvo donated some of the stones of his collection to the Regional Museum of Ica, and also unsuccessfully sought to have the region where they had been found made into a special preserve so that ancient objects could not be removed illegally.[4] The stones were exhibited at the museum, labelled as "pre-Inca burial art",[6] until they were removed in 1970[4] once Cabrera's collection and ideas concerning similar stones began to be publicized, the museum now believing them to be hoaxes.[6]

Imagery

The Ica stones are engraved with various types of images. Some images are directly incised whereas others have been made by removing the background, leaving the image in relief. The images vary from simple pictures on one side of a pebble to designs of great complexity. Some of the designs are in styles reminiscent of the historical Paracas, Nazca, Tiwanaku, or Inca cultures.[8]

Dinosaurs

Several of the stones are engraved with depictions of various extinct animals, most notably different types of dinosaurs.[6] Among the dinosaurs depicted are different theropods, sauropods, ceratopsians and stegosaurs.[5][7] Also present among the stones are depictions of pterosaurs.[5] The extinct animals depicted do not correspond to fossil finds in the region; no dinosaur remains are known from the surrounding area and several groups (such as ceratopsians) are not known from South America at all.[7]

In some cases, the dinosaurs are depicted as being hunted[4][6] or domesticated by humans.[4] Some scenes appear to depict humans engaged in something akin to pitched battles with the dinosaurs[12] and some of the depictions of hunting allegedly show humans chopping at critical nerves in the dinosaurs' spines, supposedly showing advanced knowledge of their anatomy.[4]

Many of the dinosaurs depicted on the Ica stones reflect now outdated ideas of dinosaur life appearance, corroborating that the stones are hoaxes.[5][6] One of the stones for instance show a Tyrannosaurus-like theropod dinosaur with a nearly upright posture and dragging its tail behind it on the ground; this is accurate to depictions of Tyrannosaurus in the 1960s but does not reflect the current scientific understanding of the animal.[6] Additionally, some depictions of theropods on the stones show them as having five fingers and five toes, inconsistent with fossil evidence.[14] One of the stones shows a human riding on a Pteranodon-like pterosaur, an impossible scene given that the animal likely could not have supported the weight of a human in flight.[5][15]

Humans and technology

Stone supposedly depicting brain surgery

The humans depicted on the stones, supposedly belonging to some unknown ancient Peruvian culture, are reminiscent of Incas or Aztecs.[1] Some stones have been suggested to depict anachronistic and highly advanced technology, including medical professionals performing complex surgeries, acupuncture, genetic engineering, humans observing the heavens through telescopes, flying machines,[4] and spaceships.[10] Among the surgeries depicted are heart and brain surgeries,[6] caesarean sections, and transplants of hearts, livers, and kidneys.[4]

The humans depicted appear to be different from any of the well-known ancient cultures in the area.[2] They are depicted as wearing loincloths and feather headresses[2] and when shown in scenes of warfare they carry axes and spears as weapons,[1][2] despite the advanced technology shown otherwise.[2] If a society as advanced as the one alleged to be depicted on some of the stones had actually existed in the region it is highly unlikely that the only trace uncovered of them would be the artwork on the Ica stones.[1][11] Other expected finds that could corroborate such a civilization having existed would for instance include ruins of advanced structures, garbage, as well as graves and bones, none of which has been found.[1]

Other designs

Some stones are engraved with depictions of maps of the land or the stars.[4][6] There are stones depicting acts of bestiality, some of which have been referred to as "pornographic".[4] Some stones feature images are of flowers, fish, or extant animals of various sorts;[8] in some cases the depicted extant life is out of place in Peru, such as depictions of kangaroos.[10]

Impact and investigation

Interpretation

Stone appearing to depict humans riding on a dinosaur

The Ica stones are generally considered by historians and archaeologists to have been thoroughly exposed as forgeries[3] and to be hoaxes created for the purpose of earning money off of tourist buyers.[1][2] Selling artifacts is a profitable business; even replicas of the Ica stones tend to fetch high prices online.[10] In his Encyclopedia of Dubious Archaeology, the archaeologist Ken Feder commented that the Ica stones were "one of the most transparent and absurd archaeological hoaxes ever perpetrated" and that they were "not the most sophisticated of the archaeological hoaxes discussed in this book, but they certainly rank up there as the most preposterous."[12] Current scientific understanding separates non-avian dinosaurs (dinosaurs other than birds) from humans by 66 million years and it is consequently considered highly unlikely that humans and dinosaurs could have coexisted in the manner depicted on the Ica stones.[4] No non-avian dinosaur fossil has even been dated to an age contemporary with humans.[11]

The Ica stones were popularized by Cabrera internationally and became publicized in magazines and newspapers throughout the world.[2] Some pseudoscientific communities enthusiastically accepted the Ica stones as evidence for various ideas.[1] As supposed "out-of-place artifacts", the stones have become staples of pseudoarchaeological literature.[16]

The stones came to the attention of proponents of the ancient astronauts hypothesis (the idea of extraterrestrial visitors to Earth in the ancient past) such as Erich von Däniken and Robert Charroux and were extensively publicized in books during the 1970s, claimed to present evidence of an advanced civilization before the extinction of the dinosaurs. The stones have also been used as evidence by Young Earth creationists for the idea that dinosaurs and humans coexisted in relatively recent times, fitting with their idea of an Earth only a few thousand years old.[4] Replicas of the Ica stones are sometimes showcased internationally in exhibitions by creationist institutions.[17] The stones are also sometimes presented as evidence by "mytho-historians" who believe that some ancient myths should be understood as accurate and literal historical accounts.[1] Some previous supporters of the stones' authenticity, including von Däniken, have since concluded that the stones are most likely fake.[4]

Analysis

Stone supposedly depicting a heart transplant

No formal scientific research on the Ica stones has been published.[7] Since they do not contain any organic material, the stones cannot be dated using radiocarbon dating,[1][6][7][11] meaning that any hypothesis of ancient origin cannot be tested.[7] If any stone was presented for scientific analysis in situ (at its original site of discovery in the ground) they could conceivably be dated from the surrounding material.[1] No Ica stone has however ever been found or presented in a certain and examinable archaeological context.[2]

Cabrera claimed to promote scientific analysis of the stones and claimed to have sent individual specimens to researchers at the universities of Bonn and Lima. Both a researcher at Bonn and the mining engineer Eric Wolf, a personal friend of Cabrera, supposedly confirmed that the stones are made of andesite and that they seem to be of significant age due to their oxidized patina.[6] Even if these unverified assessments of significant age for the stones is true, it would not confirm an ancient age for the engravings since there is no patina in the grooves.[4] The lack of a patina covering the sharp engravings instead suggests that they are recent.[14] In 2002 it was reported that an examination of one of the stones done in Barcelona found signs of sandpaper usage and recent engravings.[11]

Identification as hoaxes

Stone appearing to depict a map

After the stones were publicized in a critical BBC documentary, they began to draw the attention of the Peruvian authorities and press.[4] The sale of Peruvian cultural heritage is illegal and the authenticity of the stones thus became a legal matter.[4][6] After being arrested and interrogated, Uschuya admitted that the stones were hoaxes that he and the fellow forger Irma Gutierrez de Aparcana had engraved themselves and sold to Cabrera.[1][4][6] Their stated motive had been to make money from tourists[4] and to inspire pseudohistorians such as von Däniken.[6] The inspiration for the different engravings had supposedly been comic books, textbooks,[1][6] and magazines.[1] After he was let go, Uschuya continued to make and sell similar stones, though no longer passed them off as genuine.[4]

Uschuya reportedly produced the dark patina of the stones through baking them in donkey and cow dung and massaging them with boot polish. The engravings were made using a dentist's drill, knives, and chisels.[4][12] At another time, Uschuya claimed that after he had etched the artwork on the stones, he placed them in his poultry pen and "the chickens did the rest".[11] The process of making the stones has been documented by several TV crews.[14]

Despite Uschuya's confession, supporters of the stones' authenticity were not convinced that they were fakes. Doubt was cast both on his confession, suggested to have been done simply to avoid prison time, and on the idea that a poor farmer without a formal education could have made tens of thousands of stones.[4] Uschuya is not necessarily the only maker of such stones, however.[2] In later interviews, Uschuya has contradictingly corroborated that he faked the stones or stated that he simply claimed to have done so to avoid prison. In a 1995 interview for the NBC documentary The Mysterious Origins of Man, Uschuya again admitted to the hoax but also claimed that Cabrera in his collection had "about 5000 genuine stones", either real artifacts or made by someone else.[4]

There is no evidence that Cabrera colluded with Uschuya to produce fake stones or that his motivation was any other than to preserve what he thought was genuine artifacts and try to generate archaeological interest.[4] Despite Uschuya's confession, Cabrera continued to maintain that the stones were real. His explanation for this was that the stones made by Uschuya were copies or replicas of original, real, stones so that they could be sold to tourists legally.[6] Cabrera further claimed that there existed genuine hoards of stones at a secret location guarded by "Uschuya and others", including in a secret cave near the Ica River. No evidence has been presented for the supposed cave's existence[4][14] and the story is by skeptics presumed to have been made up by Cabrera.[14] Von Däniken claimed in his book Gold of the Gods to at one point have been taken to the cave by Cabrera but later admitted to have made this up when the story was disputed by Cabrera.[12]

Possibly authentic stones

It is possible that some of the Ica stones are authentic artifacts,[1][4][5] a notion for instance supported by the early Spanish records of similar stones.[1] It has been suggested that the large number of stones is an argument in favor of at least some being authentic,[4][5] though this is a dubious argument.[18] The great number of stones could alternatively be interpreted as evidence against their authenticity since it could also indicate large amounts of them having been made for the purposes of selling them to tourists.[7] Modern "Ica artists" have allegedly followed in Uschuya and Irma's footsteps in producing new forged stones, some based on their designs.[1]

No studies have been made attempting to distinguish possible genuine stones in the collections.[4] Even if some of the more outlandish stones were genuine artifacts, their motifs could plausibly depict less anachronistic scenes than what has been claimed;[4] the images are all highly stylized and what precisely is being depicted is in many cases not clear.[5] It is for instance possible that scenes interpreted as showing advanced surgery in reality show acts of mutilation and some supposed flying machines could alternatively be interpreted as birds.[4] According to the independent researcher Neil Steede, it is possible that the stones donated to the Regional Museum of Ica by Calvo are genuine since they in contrast to those in Cabrera's collection supposedly have shallower cuts, show finer workmanship, and only depict extant animals and conventional humans.[4]

In order to defend the assertion that the stones were made by an advanced civilization, Cabrera stated that andesite is a hard stone that is difficult to carve, particularly using stone tools. The stones are however not carved but engraved; the engravings were made through scratching away the surface layer of oxidation. Furthermore, many pre-Columbian cultures, including the Aztec, Inca, and Maya, had advanced metallurgy and were not limited to stone tools.[1][11]
