DNA identifies Teodomiro, founding father of the Camino de Santiago 12 centuries in the past | Science | EUROtoday

On a July afternoon, within the central nave of the Cathedral of Santiago de Compostela, the incense of the botafumeiro fills the air as hundreds of vacationers and pilgrims collect round ready to embrace the apostle. Disguising themselves in order to not entice curious onlookers, archaeologist Patxi Pérez-Ramallo opens a trapdoor nearly at floor stage and factors to a darkish staircase main down. A couple of steps down, 4 metres beneath the temple, we’re already within the ninth century.

“The first two houses in Santiago were here,” says Pérez-Ramallo. These poor quarters, constructed greater than 1,100 years in the past, quickly turned the tombs of the primary necropolis within the space, when Santiago was only a village of devotees who got here from different elements of the Peninsula searching for sanctuary. The stays of the primary wall can nonetheless be seen, and inside its partitions, a chaotic jumble of tombs: luxurious sarcophagi for the wealthy, damaged tombstones for the poor, massive graves for adults and tiny ones for youngsters, all buried with out useful objects, as a result of God needed to be clear of fabric wealth. In a number of of them the lifeless nonetheless relaxation, utterly cadaverous.

In the richest and noblest a part of this cemetery used between the ninth and Twelfth centuries, the place the lifeless even had tombstones with their names, the archaeologist Manuel Chamoso Lamas discovered Teodomiro's tombstone in 1955. It was a historic discovery that has been shrouded in controversy and thriller ever since.

Teodomiro was the bishop of Iria Flavia – now Padrón – one of many few bishoprics that remained after the Muslim invasion of the Peninsula in 711. According to legend, the prelate discovered the misplaced tomb of the apostle Santiago, a gifted disciple of Jesus, in a forest known as Libredón. Against all odds, the bishop instantly moved to this inhospitable place, the place a small temple was constructed, which King Alfonso II of Asturias visited following the shoreline, thus inaugurating the Primitive Way. It was the start of a pilgrimage that continues as we speak with nearly half one million guests who come to Santiago yearly to ponder the Portico of Glory and the remainder of the wonders hidden within the cathedral.

Until the invention of the tombstone, it was thought that Teodomiro had by no means even existed. During excavations, human stays of an individual have been discovered underneath that grave, however evaluation of the bones couldn’t decide whether or not they have been these of a person or a girl.

Almost 60 years later, in 2014, the Santiago Cathedral Foundation launched a venture to use new molecular evaluation strategies to the stays with the goal of clarifying whether or not they actually belong to the legendary bishop, with out whom the Camino de Santiago wouldn’t have existed. “We wanted a complete investigation with all the possibilities that science has today,” sums up Daniel Lorenzo, priest director of the Foundation. The venture fell to Pérez-Ramallo, a 36-year-old historian from Santiago who had labored promoting tickets for the cathedral museum, and who has specialised within the newest relationship strategies and forensic DNA evaluation within the United Kingdom, Germany and Norway, the place he at the moment works.

On a chilly November evening in 2019, after 10 p.m., Pérez-Ramallo waited patiently for the stonemasons to fastidiously take away the Teodomiro slab. Beneath it was a field that archaeologists had sealed with a layer of steel within the Fifties. A blacksmith eliminated it “as if it were a can of sardines,” remembers the Galician researcher.

First got here shavings, then a protecting fabric, and at last the cranium, ribs, and arm and leg bones of the supposed bishop, buried in 847. Along with them was a message in time left by Chamoso Lamas for future archaeologists: the sealed reminiscence that licensed the authenticity of the corpse and the difficulties in figuring out its intercourse.

The bones have been minimize off at their ends, there was no hip or face. “The skull had masculine features, indeed, but also other indeterminate ones; and in general the complexion was very graceful,” remembers Pérez-Ramallo. That evening, nothing extra could possibly be decided, and all these current agreed to not say a phrase about what had occurred there till a conclusive verdict had been reached.

Five years and a worldwide pandemic later, the outcomes of the DNA evaluation extracted from the bones, to which EL PAÍS has had entry, go away little question: the stays are these of a person. Carbon 14 relationship signifies that he died at over 45 years of age. His bodily options recommend that he was of weak structure and didn’t carry out bodily work throughout his life, which inserts with a bishop.

The relationship of a rib means that he died round 820, with a margin of error of as much as 15 years extra, which might be near the date of the tombstone. The stays are the oldest present in the complete Santiago necropolis, the place Pérez-Ramallo has analysed some 30 corpses, 10 of them with DNA, in a earlier investigation that he paid for by asking cash from his mother and father, a housewife and a mechanic who reside in Boiro.

The carbon, nitrogen and oxygen atoms collected within the bones enable us to find out what this individual ate and the place his meals got here from. The outcomes reveal that he had a really austere weight loss program, nearly monastic, however not as spartan as that of the poor peasants of the time, which inserts with a bishop who lived like a monk. The isotopes point out that he all the time lived close to Santiago, however his authentic origin was additional southwest, on the coast, proper the place Iria Flavia was. With all this information, “we can say that it is Teodomiro with a 98% probability,” says Pérez-Ramallo, a researcher on the Norwegian University of Science and Technology.

The stays held one final secret. The evaluation of the genome reveals a big ancestry from North Africa. Previous research have seen the identical mark in present-day Galicians, which is a thriller. It is feasible that it’s the affect of crossbreeding with Muslim invaders, however in accordance with Pérez-Ramallo's staff it’s too sturdy an indication and unique to Galicia. This territory was not conquered by the Muslims, though Almanzor destroyed the Romanesque basilica that preceded the cathedral of Santiago, in 997.

The most believable, argues Pérez-Ramallo, is that Teodomiro's grandparents or great-grandparents have been descended from Romans who lived in North Africa in the course of the Empire. Centuries later, within the eighth century, the bishop's ancestors have been capable of cross the Strait with the Muslim invaders and went over to the Christian zone. There Teodomiro grew up, lived and died subsequent to a humble temple erected in honour of Santiago which at the moment was “nothing”, in accordance with the priest Lorenzo, however which turned a spot of pilgrimage that rivalled Rome and Jerusalem. The analysis, led by Pérez-Ramallo and in addition signed by worldwide authorities similar to Tom Higham, an knowledgeable in carbon relationship from the University of Oxford, is printed as we speak within the specialist journal Antiquity.

CSIC geneticist Carles Lalueza-Fox, who was not concerned within the analysis, highlights its worth. “This is a new example of personal historical genomics, similar to previous studies with the remains of Beethoven or Richard III; over time it will become a scientific field of its own that will allow us to reinterpret many characters,” he highlights. In 2019, Lalueza-Fox managed to learn the DNA of the French revolutionary Jean Marat because of the bloody newspaper that the Jacobin chief was studying earlier than being stabbed to dying. In the case of Teodomiro, the researcher factors out, the one technique to make an incontestable identification could be by analysing the DNA of dwelling or lifeless relations, which is a big problem for a bishop who lived 12 centuries in the past.

The subsequent step can be to deposit, this time completely, the stays of Teodomiro collectively along with his tombstone, in a clearly seen place within the cathedral. Would or not it’s attainable to do the identical DNA evaluation with the stays of the supposed Santiago El Mayor, who in accordance with the Bible died across the yr 44, whose stays arrived in Galicia in a stone boat, in accordance with legend, and now relaxation in a reliquary subsequent to these of his two disciples Teodoro and Atanasio?

The brief reply is not any. For a number of causes: one in every of them is that there could be no manner of figuring out who every bone belongs to, Lorenzo argues. The different is that the papal bull recognizing the authenticity of the stays of Santiago, issued by Pope Leo XIII in 1884 after their rediscovery within the nineteenth century, determines that they can’t be touched. Only the pope may give the order to open the relic and, in doing so, would endlessly distort the legend that helps the trail.
