On the western bank of the Euphrates, near the border of modern day Iraq and Syria, once stood the ancient walled town of Dura-Europos. Founded as a military colony by Selecus I Nicator, one of Alexander the Great’s successors, Dura-Europos became a sprawling city, serving as a crossroads of cultures and empires. Under Roman rule, the city became one of the most strongly fortified points on the eastern border with the Sassanid Persians. In the year 256 AD, the Sassanid King of Kings, Shapur I, laid siege to the city. The siege was extremely violent, with the Sassanids trying multiple times to undermine Roman defenses. The Persians may have also used poisoned gas, stemming from ignited sulphur crystals, in order to kill the roman defenders, in what is an ancient example of chemical warfare. The skeleton of the Sassanid soldier who was most likely responsible for the release of the gas was found by archaeologists. Even a siege ramp was erected by the Sassanid troops in order to breach the defenses of the city. Eventually the Sassanids did manage to take the city, deporting the survivors to Ctesiphon and selling them as slaves. The city then became a ghost town, as emperor Valerian was defeated and captured by Shapur’s forces near Edessa in 260 AD and therefore could not intervene in time. Desert sands would gradually cover the city’s buildings, miraculously preserving them for future archaeology. Evidence of Dura’s cultural diversity throughout the centuries can be found in the retrieved works written in Greek, Latin, Palmyrean, Hebrew and Middle Persian. The city contained a Christian chapel, a Synagogue, a Mithraeum and an Agorà, proof of the greek/macedonian origin of the town. Dura also housed a Roman military camp, the base from which the Roman garrison operated the defense of the walls in 256 AD. The extensive archaelogical evidence (which included also many pagan temples, the Praetorium and the city walls) present in the town led to the city being called: “the Pompei of the Desert”. Contemporary satellite images show that 70% of the site has been destroyed by looters and by ISIS operations in the region. One of the guards of the archaeological site has been beheaded. Dura-Europos is now lost to the the desert winds of Eastern Syria.
