The ” ‘Ica’ ” stones are a set of 15,000 pebbles of etesite engraved, appeared in Ica in Peru in the 1960s. The engravings represent fantastic animals, dinosaurs cohabiting with human beings, scenes evoking advanced technologies (surgical operations, heart transplants, telescopes, rockets, etc.). At first presented as authentic archaeological objects by their inventors, they finally prove to be a hoax.
Ica stones are made on andesite pebbles of various sizes. They are engraved superficially and carry various scenes and drawings, maps, missing animals such as dinosaurs or complex medical practices.
Some authors, like Professor Alejandro Pezzia Assereto, spoke about the stones of Rio Ica a few years before their media coverage. In 1966, an engraved stone is offered to the Peruvian doctor Javier Cabrera Darquea for his by his friend, the photographer Felix Llosa Romero. Cabrera recognizes the design of an extinct fish for millions of years. His father began a collection of similar stones in the 1930s, Cabrera, which is interested in the prehistory of Peru, also undertakes a collection. He bought 341 pieces from two brothers, Carlos and Pablo Soldi, who hold thousands of similar stones from the neighboring region of Oucaje that they tried, unsuccessfully, to offer to archaeologists. Subsequently, Cabrera discovers another source of stones engraved with a farmer, Basilio Uschuya, who sells him thousands. Cabrera’s collection reached more than 11000 objects in the 1970s. He published the book The Message of the Engraved Stones of Ica (“The Message of the Engraved Stones of Ica”) where he expounded his theories on the origin and meaning of stones. In particular, he defends the idea that humans have been around for at least 405 million years and that people from another planet have created humans by implanting cognitive codes with higher intelligence primates. The stones were used by some creationists who tried to show that humans rubbed non-avian dinosaurs, an allegation for which no scientific evidence exists and which contradicts the well-established date of extinction of non-avian dinosaurs, about 65 million years ago compared to the appearance of humanity. Some ufologists also use them as an argument in favor of the theory of ancient astronauts: stones would prove the existence of an ancient, technologically advanced vanished civilization. Some mytho-historians have also used them as proof of the veracity of ancient myths.
In an interview with Erich von Däniken in 1973, Uschuya admits to engraving the stones. In 1975, Uschuya and a farmer named Irma Gutiérrez of Aparcana confirmed that they were the authors of the trickery: they engraved the stones proposed in Cabrera by copying images of comics and magazines. Uschuya then retracts in an interview with a German journalist, claiming that he claimed to be the author of the engravings to avoid a prison sentence for the sale of archaeological remains. In 1977, for the BBC documentary Pathway to the Gods, Uschuya made an Ica stone using a dentist’s burs and said he had made the patina by baking the stones. in cow dung; the same year, another report from the BBC offers a skeptical analysis of Cabrera stones. The renewed attention to the phenomenon is prompting the Peruvian authorities to stop Uschuya for sale of archaeological finds. Uschuya retracts again, stating that the objects are fraudulent: He actually grates the stones using pictures of books and magazines as templates and using knives, scissors and a dental drill. He indicates, however, that he is not the author of all the engravings. He escapes conviction and continues to sell stones similar to tourists as trinkets. Stones are still made and engraved by other artists as counterfeit counterfeits. Cabrera abandons his medical career in 1996 and opens a museum in Ica, Peru, where several thousand engraved stones can be seen. In his Encyclopedia of Dubious Archeology: From Atlantis To The Walam Olum, archaeologist Ken Feder states:.
