Vienna, 9 May 2021
My wife and I went for a hike recently along a section of the Jakobsweg, the Trail of St. James, one of the network of pilgrim trails that lead from all over Europe to Compostela in north-western Spain. This particular Trail of St. James starts in Hungary and leads the pious walker to Vienna. From there, it goes on along the Danube, joins the Jakobsweg coming down from the Czech Republic (parts of which we hiked last year), and then wends its way across the Alps.
The particular section we walked this time took us through the village of Petronell, which lies not too far from the Danube River, downstream of Vienna. It also happens to be quite close to the remains of the old Roman town of Carnuntum, which was in its heyday (about 50 AD to 374 AD) an important hub in Rome’s line of defences along its Danubian border. Just to give readers an idea of its importance, the Emperor Marcus Aurelius used it as his headquarters for three years during his war against the Marcomanni in the early 170s (and wrote part of his Meditations there), Septimius Severus was proclaimed emperor there by his soldiers in 193, while in 308, Diocletian chaired a historic meeting there, with his co-emperors Maximian and Galerius, to resolve the rising tensions within the tetrarchy. Over the centuries, several Legions were stationed at Carnuntum: the 15th Legion “Apollinaris”, the 10th Legion “Gemina”, the 7th Legion “Gemina”, and the 15th Legion “Gemina”. A civilian town sprang up around the Castrum, no doubt aided by the fact that the main branch of the very profitable Amber Road, which I’ve written about in an earlier post, crossed the Danube at Carnuntum and entered the Roman Empire, bringing Baltic amber to Aquileia in what is now north-eastern Italy. The town eventually became the capital of the local Roman province, Pannonia. At its height, it boasted a population of 50,000.
All came to an end for Carnuntum in 374, when the town – already badly damaged by an earthquake in 350 – was put to the sword by a host of “barbarians” who crossed the Danube. By then, the Roman Empire itself was decomposing. Within a century it was all over for its western portion.
The modern trace of the Jakobsweg takes the walker past this mouldering remain of Carnuntum’s greatness.
It is the Heidentor, or Heathens’ Gate, a triumphal arch that stood on the outskirts of the town. The information board proudly informs us that it is the largest Roman remain in Austria. Indeed, the other remains in the country hardly poke out above the ground – archaeologists have had to dig them out. Here are other remains of Carnuntum.
These are remains of Vindobona, which is now Vienna
And these are remains of Juvavum, which is now Salzburg
It gives me pause to see so very little left of what was once a great Empire. If you superimpose the Peutinger map, the old Roman map of the Empire’s road system, onto today’s Austria, you can see that the Romans had quite a presence in the country.
Yet hardly a trace of any of this remains now. “How are the mighty fallen!” laments David in the Book of Samuel. And indeed how far has mighty Rome fallen.
Around the Heidentor is a wind farm.
The windmills, wonders of modern technology, tower over the countryside, their blades slowly turning in the wind.
They are part of our line of defence against the greatest existential threat which our planet faces, climate change. Will we succeed in reining in climate change, I wonder? Or will we fail and see our civilization, like the Western Roman Empire before it, crumble under the strain of the resulting economic dislocations and social disorders? These mighty works of our civilization will eventually come tumbling down – some already have.
Perhaps a thousand years from now, when our civilization will have been forgotten during the dark ages which will follow its collapse, descendants of the few who managed to survive will stumble across the ruins of these windmills, covered in brambles and ivy, and they will stand there marveling, wondering what they were all for.
