Canary Islands, SpainFrom the cliffside path that leads down to the sea, about four kilometers away, I come to a halt. This is the spot: a cave, its entrance barely visible. I look up at the looming face of the rock. I sense it staring back at me, beckoning with its stash: hundreds of caves, built over the centuries from the lava flows of Mount Teide. Any one of them could be the cave we’re looking for—here, history has not yet been written. Within this gorge in southern Tenerife, the largest of Spain’s Canary Islands, a stunning cave was found in 1764 by Spanish regent and infantry captain Luis Román. A contemporary local priest and writer described the find in a book on the history of the islands: “A wonderful pantheon has just been discovered,” José Viera y Clavijo wrote. “So full of mummies that no less than a thousand were counted.” And thus the tale of the thousand mummies was born. (Read about the different types of mummies found worldwide.) Few things are more exciting than navigating the ambiguous edge between history and legend. Now, two and a half centuries later, in the gorge known as Barranco de Herques—also called “ravine of the dead” for its funerary caves—we find ourselves in the place that most local archaeologists consider to be the mythical “cave of the thousand mummies.” There are no written coordinates; its location has been passed on by word of mouth among a chosen few. The hikers who venture along the path are oblivious to its existence. The archipelago's volcanic underpinnings created a system of lava tubes on Tenerife—an ideal environment for entombment.

In the company of islander friends, I feel privileged to be shown the place where they believe their ancestors once rested. I crouch toward the narrow opening, turn on my headlamp and drop to the ground. To find this hidden realm, we crawl in on our stomachs for a few claustrophobic meters. But there’s a reward for subjecting ourselves to the tight squeeze: a tall, spacious chamber suddenly opens before me, holding the promise of a journey to the island’s past. “As archaeologists we assume that the expression ‘thousand mummies’ was probably an exaggeration, a way to suggest that there were indeed a lot, a whole lot—hundreds,” says Mila Álvarez Sosa, a local historian and Egyptologist. In the darkness, our eyes slowly adjust. We survey the space for the telltale signs of a necropolis in the meandering lava tube, part of an extensive system across the island. These weren’t the first mummies to be unearthed on the island. But according to local lore, a large sepulchral cave like this one held the pantheon of the nine Mencey kings who ruled the islands in precolonial times. The cave’s location was a scrupulously guarded secret. And there was no record of it, which only served to elevate it as the holy grail of Canarian archaeology. Locals maintain they don’t disclose the location in order to protect the memory of their ancestors who rested there, the Guanches, the Indigenous people of this island—no distinct Guanche population remains today. Others say it was lost to a landslide, buried forever. (Go beyond the beaches in the Canary Islands.) What may have been a certainty for those 18th century explorers morphed into legend when the mummies were plucked from their resting place and their location was lost. But the precious few—from that cave and others—that remain intact and are held in museum collections are helping scientists unravel the story about the archipelago: when and where the first inhabitants came from, and how they honored their dead. Printed in a 1746 book, this etching of a burial cave in Tenerife was based on the account of a Welsh doctor who claimed he visited the site. It matched the description of a necropolis discovered by a Spanish captain some 20 years later—dubbed the cave of the thou...Read MoreRead More Charles-Nicolas Cochin, Antiqua Print Gallery / Alamy Please be respectful of copyright.

It wasn’t the first confrontation the islanders had with Europeans, but it would be the last. Álvarez Sosa imagines the stark contrast when at the end of the 15th century, the dawn of the Renaissance, soldiers sailed in on ships and wielded swords on horseback. They came face to face with a people just emerging from the Neolithic era, cave dwellers who wore animal skins and used tools made of sticks and stones. “But yet they honored their dead, preparing them for their last trip,” Álvarez Sosa says. “They preserved them.” The afterlife Mirlado is the name of the process early inhabitants of Tenerife and Gran Canaria used to preserve their mummies. The work was done by professional embalmers, and the families of the deceased transferred the body to its final resting place. Mummification in the archipelago was distinct from Egyptian practices. Dragon tree resin Animal fat 1 Tuff rock The body was cleansed with water and herbs to remove impurities. It was then coated with animal fat to intensify the sun’s power. Pumice stone dust 2 Pine and heather bark A mixture of minerals, herbs, tree bark, and dragon tree resin—often referred to as blood because of its reddish hue—was applied to every inch of the body’s surface to halt decay. Volcanic ash and lapilli were inserted through the mouth, rectum, and small incisions between the ribs to stop internal decomposition. Lapilli Aromatic herbs 3 The dehydration process took 15 days and involved laying the body on hot sand in full sun during the day, and exposing it to smoke from a fire at night. 4 At the end of the drying process, family members wrapped the body in goatskin and took it to its final resting place in one of the caves or lava tubes within the extensive system created by the feared Teide Volcano, where conditions would facilitate its preservation.

Sources: Mila Álvarez Sosa; Guanche Mummies, Story Productions A fascination with death led the colonists to chronicle the funerary ritual in detail. “That’s what mainly caught the attention of the Castilian conquerors,” says Álvarez Sosa. In particular, they were intrigued by the embalming process—mirlado—that prepared the xaxos, as the Guanche mummies were called, for eternity. The cave walls are silent. Submerged in the darkness, I imagine the awe Luis Román must have felt when, imbued with the spirit of the Enlightenment and accompanied by locals, he entered the necropolis on a mission to retrieve a few specimens for study. He transported the bodies to Europe where, by the 18th century, mummies represented a scientific curiosity as well as a novelty; both scholars and collectors took an interest. I picture the moment Román raised his torch, revealing hundreds of bodies frozen in time. He must have been overcome by a mixture of sacrilege and exhilaration. Curiously the writer who summarized a report of their visit omitted the location. If the intention was to preserve the cave from plunder, he regrettably failed: by 1833 multiple sources confirmed no bodies remained. (Learn more about Egypt's royal mummies.) I stand up and shake the white dust from my hands and knees. My headlamp dimly illuminates the walls. Though I know there’s not even a remote possibility, in my heart I still long to spot a xaxo (pronounced haho) in some nook or cranny, just like Viera y Clavo described. The method for preserving these corpses for their battle against time and nature was surprisingly simple. “It’s the same process you would use with food,” says Álvarez Sosa. “The bodies were treated with dry herbs and lard and were left to dry in the sun and smoked by fire.” It took 15 days to prepare a xaxo, compared with 70 for an Egyptian mummy (40 days to dehydrate in naturally occurring natron salt, then 30 days of embalming in oils and spices before the cavity of the corpse was filled with straw or cloth and wrapped in linen). Another key difference: according to chronicles, for propriety women in the Canary Islands participated in the process, handling female corpses.

Later, the family of the deceased handled the xaxo, placing it in a cured and carefully stitched bag made of animal hide—usually goat. The number of hide layers corresponded to the person’s social standing. The practice wasn’t limited to Tenerife. Mummies have also been found on neighboring Gran Canaria island, decorated with etchings or painted in multiple hues, wrapped in a reed mat, and then deposited in hollow tree trunks. Corpses also have been found there in funerary caves. “We still have many questions—and few samples to study,” says archaeologist María García, curator at the Institute of Bioanthropology in Santa Cruz de Tenerife. She’s painstakingly catalogued the history, dates, and origin of the remains of the 30 or so xaxos in the institute’s drawers. In this immaculate morgue, the bodies of men, women, and children slumber in repose, just steps from one of the city’s thriving thoroughfares, Noria Street. These xaxo remnants were found by hikers and shepherds across sites in Tenerife. So the question lingers: What happened to the ‘thousand mummies’? Or was it all a fabrication? “It was systematic plunder,” María García says bluntly. “During the 17th and 18th centuries the mummies were a lure for the European cultured classes. Our xaxos traveled around the world to be placed in museums and private collections, and some were even ground into aphrodisiac powders.” Others might have ended up at the bottom of the sea, Álvarez Sosa posits in her book Tierras de Momias (Lands of Mummies), probably thrown overboard when balmy conditions on the ship activated the decomposition process during the trip to the Continent. (What surprising new clues are revealing about ancient bog mummies.) Despite having the intact Guanche mummy and remains of three dozen more, we know very little about their tombs. “No archaeologist has ever found a xaxo in its original environment,” María García explains. A CT scan performed in 2016 on the same mummy—the best example of the 40 in museum collections—in a Madrid hospital allowed researchers to peer into its interior without damaging its structure.

SEEKING ANSWERS This is not the first time I traveled to the Canaries seeking answers. Eight years ago I rappelled down a cliff face in the gorge, peering into a dozen caves in search of the legend. I reread 15th- and 16th-century chronicles and interviewed experts to unravel the origins of the early Canarians. These were the mythical Fortunate Isles where ancient Mediterranean seafarers had once landed. The Europeans who later encountered the islands in the Middle Ages found that unlike other Atlantic archipelagos, these islands were inhabited, their populations seemingly isolated for centuries. Chronicles spoke of tall Caucasians, which sowed the seeds for now refuted hypotheses: they alternately descended from shipwrecked Basque, Iberian, Celtic, or Viking sailors. I left the island without coming much closer to any answers. But now modern technology has put an end to the enigma that lasted for centuries. The mummies have spoken.

Photographs by Fernando Velasco Mora Courtesy of the National Archaeological Museum, Madrid If the place I'm now exploring is the cave described by Viera y Clavijo, this is where the mummy at the top began its long voyage. The circuitous tale begins in 1764, when it was shipped to Madrid as a gift to King Charles III for the court to take in the workmanship of the Guanches in sending their dead to eternity. In 1878 it was on exhibit at the Paris World’s Fair, before it was returned to Madrid, where it lay for over a century in what is today the National Museum of Anthropology. In 2015 it came to its current resting place, the city’s National Archaeology Museum. One night in June 2016 under tight security the mummy was taken on its shortest outing ever: to a nearby hospital for a CT scan. “We had already had CT scans of several Egyptian mummies,” says Javier Carrascoso, associate chief of radiology at Madrid’s QuirónSalud University Hospital, which offered to extend the technology to the Guanche mummy. The scan provided data that debunked a hypothesis that they had simply dehydrated naturally as well as the theory that the Guanche mummification process was derived from Egypt, some 3,000 miles away. (Learn how mummies show clues to ancient diseases.) “It was impressive,” says Carrascoso. “The Guanche mummy was much better preserved than the Egyptian [ones].” The definition of its muscles could still be observed, and the hands and feet in particular were outlined in detailed relief. “It looked like a wooden sculpture of Christ,” he says. But the most remarkable finding was hidden: unlike its Egyptian counterpart, the Guanche mummy had not been eviscerated. Its organs, including the brain, were perfectly intact thanks to a mixture—minerals, aromatic herbs, bark of pine and heather, and resin from its native dragon tree—that halted bacteria and thus decay, inside and out. Radiocarbon dating in 2016 revealed a tall, healthy male, perhaps a member of the elite, given the condition of his hands, feet, and teeth. He was probably between 35 and 40 years old when he died around 800 to 900 years ago, well before the Castilians arrived. The spine showed a dysmorphia common among North African populations, and his facial features also pointed to the neighboring continent.

Rosa Fregel, a researcher at the University La Laguna in Tenerife who has studied the islands’ early populations for years, applied the latest DNA sequencing techniques to remains of 40 xaxos. The findings correlated with earlier testing, leaving no doubt about the mummies’ kinship with North Africans: the first inhabitants came from the Maghreb—the continent’s northernmost reaches along the Mediterranean. That doesn’t mean they came from the same place or at the same time. “We’ve discovered that the populations in each of the islands have their own peculiarities,” she explains, so the archipelago wasn’t necessarily homogeneous. AFRICAN ORIGINS Etymology, epigraphy, and ethnohistoric sources had already pointed to African origins, and science now concurs. Centuries before the arrival of Islam to the region, North Africa was inhabited by Numidian clans. The Greeks and Romans disdained them as Berbers—“barbarians”—while the Numidians called themselves Amazigh, or “free men.” They were farmers and animal breeders, and some arrived in the archipelago with their trades and their domestic animals. Why did they abandon their homes in North Africa? And how did they reach these islands, about a hundred kilometers from the coast? “We have always talked about waves of immigration,” says Teresa Delgado, curator of the Canarian Museum in Las Palmas. “But maybe it was just groups of families arriving at different times. Maybe events in North Africa, from Roman rule until the arrival of Islam, triggered periods of migration.” According to José Farrujia, an archaeology and history professor at the University of La Laguna in Tenerife, seven of the eight islands have been continuously inhabited at least for the last 10 centuries. Their populations shared physical traits, and their now extinct languages evolved from Libyan Berber. Farrujia also points out that cave paintings found in the archipelago are similar to ones found in Western Sahara, Algeria, and Morocco’s Atlas Mountains. The first known images of the early islanders came from Italian engineer Leonardo Torriani, dispatched to the archipelago by the Spanish crown to plan fortifications. His maps and drawings, including one from Gomera, above, were published in a book around 1590.

Historians have put forth various emigration theories. According to one scenario, the islands’ first inhabitants were banished Berber rebels brought to the islands between 25 B.C. and 25 A.D. during the Berber revolt against Rome. “Roman law used banishment to the islands as a punishment,” says Antonio Tejera Gaspar, who’s written about the clash. “Ever since the fall of Carthage, the whole region became a powder keg.” The king who banished the rebels, he believes, was Juba II. Many historians agree that Juba II, son of the defeated Numibian king Juba I, discovered the Canaries. He was educated in Rome and married Cleopatra Selene, the daughter of Cleopatra and Marc Antony. In an effort to assimilate the population, Augustus put the couple in charge of Mauritania, which extended from today’s Tunisia to Western Sahara. A scholar, writer, and naturalist, king Juba widely explored his territory and some outliers: According to an account in Pliny the Elder’s Natural History, Juba’s chronicles—since lost—note an expedition to the Fortunate Isles in 46 B.C. It’s the first time the islands are named, and he refers to one of them as Canary. He describes the natural features of each of the islands. “And if he does not mention their people it’s because they were not inhabited,” Tejera Gaspar says. That would come within the next century, when Rome banished the insurrectionists, he notes. Tejera Gaspar argues that the colonists weren’t after resources or riches since the islands lacked both. LINGERING QUESTIONS Or maybe not. Another theory emerged after the 2012 discovery of pottery shards on the small island of Lobos, suggesting that early colonizers may have frequented the islands for their natural resources. Archaeologists uncovered pots, lanterns, hooks, and harpoons, imported and made of non-native materials, including some originating in Andalusia—artifacts typically found along the western Mediterranean trade routes. Shellfish deposits found in the same area led some researchers to believe that seasonal workers landed in temporary settlements to harvest Stramonita haemastoma, a mollusk used to make the prized Tyrian purple dye, reserved for Roman emperors. “A workshop to produce the purple dye demonstrates that the archipelago was within the Roman sphere, that the territory had been explored,” explains María del Carmen del Arco, an archaeologist at the Lobos site, which has been dated to the Roman period. She also points out that Roman ships could have transported new biological stock in the form of animals, plants, and people. (Read how South American cultures made their own mummies.) Still, Carmen del Arco says Pliny the Elder mentions an earlier population predating the Roman era, and archaeology backs up those dates. Some sites in Tenerife have been dated to the 6th century B.C. and in La Palma, the 3rd century B.C. “It all makes sense, especially if we consider that the islands were populated from east to west, from the nearest to the farthest from the African coast,” says José Farrujia. Farrujia describes cave paintings on several of the islands depicting boats similar to the Phoenician ones. “Nothing tells us that they did not know how to sail,” says Farrujia. “There probably were boats, but perishable materials do not leave archaeological traces.” It’s also likely that people might have been enslaved and brought involuntarily by boat, which then departed.

Unauthorized use is prohibited. Some scholars maintain radiocarbon dating on these sites is inconclusive. And human remains found on the islands so far do not predate the 4th century A.D., as Conrado Rodriguez, director of Tenerife’s Museum of Nature and Archaeology notes. The confirmation of the ancestry of the early inhabitants has renewed archaeology efforts, which may turn up evidence. Who are we? Ultimately everything comes down to a quest to understand our origins. The answer may lie within an unexplored cave, a necropolis, an etching. The island’s topography—its gullies and ravines, hardened lava flows, caves, and windblown sands—helps preserve those secrets. I turn off my headlamp and find refuge in the absolute silence that shelters me like a uterus. I feel no cold, no heat, no fear. I have come seeking answers, and I take away the gift of knowing that questions still remain. My colleagues, all Canarians, produce an old ceramic bowl they call a ganigo, similar to the ones from which the Guanches drank milk to seal their pacts. They ask me a simple question: Do you swear not to tell anyone the location of this cave? In the darkness I cannot see their eyes, yet I know they are shining with the same excitement as mine. With them and the souls that for centuries populated this cave as my witnesses, I answer: Yes, I swear. Emma Lira is the author of Búscame donde nacen los dragos, a historic novel set in Tenerife.
