Aachen, 1000 and the Legend of the Last Emperor
In the spring of the year 1000, excavations took place in the great church of Aachen, built by Emperor Charlemagne of the Franks, who had died nearly two centuries previously. The excavations had been commissioned by one of Charlemagne’s imperial successors, Emperor Otto III, with the aim of discovering Charlemagne’s final resting place.
According to three separate accounts of what happened (on which see below), this early medieval Time Team dig was brilliantly successful, and the living emperor gazed upon the dead. But what none of the accounts quite spells out, and what therefore remains an open question, is exactly what Otto III was hoping to achieve through his archaeological enquiries. Was it just idle curiosity about his distant predecessor – or was there some deeper motivation at work?
Emperor Otto III has long had a special reputation. The son of the Byzantine princess Theophanu, this half-Greek Holy Roman emperor took his role very seriously, despite (or perhaps because of) his youth. Contemporaries alleged that he preferred Italy, and especially the city of Rome, to his ancestral lands across the Alps.
For some modern historians, Otto was a dreamer, carried away by his impossible vision of reviving the Roman Empire in a very post-Roman world, and increasingly out of touch with fundamental political realities.
More recently, Otto III has been brought back to earth, as historians have asked whether he really was quite as ideologically driven (and unrealistic) as all that. Maybe the ‘programme’ of Roman renovation that historians such as P.E. Schramm have attributed to him was not quite as coherent as they supposed.
Yet that doesn’t explain what Otto thought he was doing in Aachen in the year 1000. One explanation is that the excavations were part of an attempt to canonise Charlemagne, in other words to have the old emperor recognised as a saint. But there is another intriguing possibility: that Otto was motivated by the legend of the Last Emperor.
The roots of this legend were older even than Charlemagne himself – they lie in the horrified reaction of Syrian Christians to the rise of Islam, and the dramatic near-collapse of the Byzantine Empire, in the seventh century. These events were so bewildering that they only made sense in an eschatological framework – as a step towards the inevitable ending of the world.
Around 692, an author claiming to be a fourth-century bishop named Methodius wrote a ‘prediction’ that the sons of Ishmael would take over the world, and impose unbearable tax demands. But ‘Methodius’ added a note of reassurance: the king of the Romans would return in the end, driving out the intruders and bringing peace and justice – until the Antichrist appeared, at which point the Apocalypse would unfold according to God’s plan.
"And after these things the king of the Romans will come down and he will dwell in Jerusalem for a week and a half of years, which is ten and a half years, and when ten and a half years are completed, the son of perdition will appear."
This text, known as the Apocalypse of Pseudo-Methodius, helped overturn centuries of suspicion about the Empire’s role in world history. It influenced many other texts, such as the Tiburtine Sibyl – another work of pseudo-prophecy which survives only in an eleventh-century version. Early Christians had been reluctant to attribute any positive eschatological role to Roman emperors, understandably enough given the history of persecutions. Now, emperors and empire could play a full, active and positive role in world history: Imperial time could be folded into Christian time.
The extent to which the year 1000 represented a high point of apocalyptic tension – a thousand years after Christ’s birth – has been debated for years, as has the extent to which Otto would have been personally affected by such concerns. But several contemporary sources – for instance Otto’s own imperial diplomas, as well as hagiographical accounts – do imply that he had eschatological thoughts in his mind in that year, as Levi Roach has recently argued. Did Otto III think Charlemagne was the Last Emperor? Did he think he himself was the last emperor?
Here are the three eleventh-century texts describing Otto’s Indiana Jones-style search for the lost emperor in Aachen, so you can make up your own mind about what Otto was doing (all the translations are mine). They were written by authors from different parts of early medieval Europe, namely a Saxon bishop and two monks – one from northern Italy, and another from southern France

Book III, Chapter 32:
After many years had passed, Emperor Otto III came to the region where the remains of Charlemagne rested in his tomb. Otto travelled to the site of the tomb itself, with two bishops and Count Otto of Lomello. The emperor himself was the fourth person. The count used to tell what happened, saying ‘We entered to see Charlemagne. He was not lying down, as is normal for the corpses of the deceased, but was sitting on a kind of throne as if alive, crowned with a golden crown, carrying a sceptre in his gloved hands, through which his fingernails had broken. There was above him a small building (tugurium), carefully built from limestone and marble. When we came to this, we knocked a hole through it. And when we had passed through the hole, we smelled a very strong odour. We at once venerated him on our knees, and Otto immediately dressed him in white garments, cut his fingernails, and made good all that was lacking around him. Nothing had decayed from his limbs, but there was a little missing from the tip of his nose. Otto at once replaced it with gold. He took one tooth from Charlemagne’s mouth, rebuilt the building, and left.’

Book III ch. 31:
At this time, Emperor Otto was warned in a dream to raise up the body of the Emperor Charlemagne. He was buried at Aachen, but because of the oblivion of passing time, no one knew exactly the spot he was buried. After fasting for three days, they found him at the precise spot the emperor had seen in his vision, sat on a golden throne in a vaulted crypt underneath the church of St Mary, crowned with a crown of gold and precious jewels, holding a sceptre and a sword of pure gold; as for the body itself, it was found to be uncorrupted. He was raised up and shown to the people. Then, one of the canons of that place, Adalbert, who was very big and tall, put on the crown of Charlemagne, as if to try it for size. It was apparent that his skull was narrower than the emperor’s, and that the dimension of the crown exceeded that of his head. He measured his leg against the emperor, finding himself to be smaller – and at once by the effect of divine power his leg was broken. He survived for forty years, but always remained crippled. The body of Charlemagne was placed in the right transept of the church, behind the altar of John the baptist. A great gilded vault was built there, and the remains began to shine out with signs and miracles. But they are not the object of any liturgical cult (sollemnitas), apart from that of the anniversary of the dead, as is the normal custom. Emperor Otto sent Charlemagne’s golden throne to King Boleslav in exchange for relics of Saint Adalbert.

Book IV, chapter 47:
The emperor [Otto III] wanted to renew in his time the ancient customs of the Romans, then for the most part destroyed, and so he did many things, about which different people had different opinions. He sat alone at a table made into a semicircle, at a higher place than the others. As Emperor Otto III was unsure about the location of the bones of Emperor Charles, he secretly had the pavement ripped up where he thought they were and ordered excavations, until they were discovered on the royal throne (solium). He took the gold cross which hung around the emperor’s neck and part of his clothing, which remained uncorrupted, and he replaced the rest with great veneration.
