Apollodorus of Damascus

• 1. Introduction

  ›

  Apollodorus of Damascus built a bridge across the Danube wide enough to carry an army. He raised a column in Rome that had never been attempted before. He engineered a forum so vast it reshaped the very center of the capital. And then, if one ancient account is to be believed, he was killed by the emperor who came after the one he had served. Who was Apollodorus of Damascus, and how did a man from Roman Syria come to define an era of Roman building? What was the cultural thread that ran from Damascus to the Danube? And what do we actually know about his end?

• 2. From Damascus to Rome

  ›

  Apollodorus was born in Damascus, in the province of Roman Syria. Modern scholars describe him variously as Nabatean, Hellenized Nabatean, Arab, or Greek, and neither Cassius Dio nor Procopius, two historians of antiquity who wrote about him, thought his origins worth specifying. Some scholars suggest that the name Apollodorus was itself a Hellenized form of the Nabataean names "Abdal" or "Abodat".

  The stylistic and grammatical weaknesses in his Greek inscriptions suggest Greek was not his mother tongue. Whatever his precise background, his early career was that of a military engineer, not a builder of temples and forums. It was in Syria that the future emperor Trajan may have first encountered him. When Trajan was consul, in 91 AD, he summoned Apollodorus to Rome, and the architect made the journey after his twentieth birthday. The professional bond that followed would shape the city of Rome itself.

  Trajan's Forum was one of the great works Apollodorus designed and oversaw in Rome. He also built Trajan's Markets, the Temple of Trajan, and Trajan's Column, described in the sources as the first monument of its kind. The column alone was a formal innovation with no precedent in the Roman tradition.

  Outside Rome, the scale of his output was equally striking. He designed Trajan's Bridge across the Danube, the Alconétar Bridge over the Tagus in Spain, the triumphal arch at Benevento, the Arch of Trajan at Ancona, and Trajan's Trophy near Adamclisi in Romania. He also wrote a technical treatise on military siege engines, the Poliorcetica, dedicated to an unnamed emperor who was most likely Trajan. Apollodorus accompanied Trajan during the Second Dacian War in 105 AD, a campaign for which engineering capacity was essential. His Danube bridge was part of that same war effort, carrying Roman legions across one of the widest rivers in Europe.

• 4. Roots of a Style

  ›

  Fiorella Festa Farina, director of the museum in Damascus, argued that the technical mastery Apollodorus brought to Roman architecture grew directly from his cultural origins. She held that his particular skill derived from Nabataean culture filtered through Greek modes of thought. That fusion produced a practical, robust approach to construction that set him apart.

  Apolodorus is credited with introducing several Eastern innovations to the Roman Imperial style. Chief among these was the dome. It was likely his influence that made the dome a standard element in Roman architectural practice, a shift that would echo through centuries of building across the Mediterranean world. He is one of the very few architects from antiquity whose name survived at all, which speaks to both the scale of his projects and the impression they left on those who documented them.

• 5. Hadrian and the End

  ›

  Cassius Dio, writing of events after Trajan's death, reports that Apollodorus offended the new emperor Hadrian by dismissing and ridiculing Hadrian's own attempts at architecture. The consequence, Dio says, was banishment and then death. That account has not gone uncontested. Many modern historians express doubt that the episode happened as described.

  The historian Jona Lendering points to two reasons for skepticism. Early in Hadrian's reign, the emperor was occupied with threats to his power far more serious than a slight from an architect. Lendering also notes that the criticism Apollodorus offered was apparently acted upon, which hardly fits the picture of a ruler so stung by mockery that he ordered a man's death. The truth of Apollodorus's final years remains uncertain, lodged somewhere between Cassius Dio's dramatic telling and the more measured view of modern scholarship. What is not in doubt is that his Danube bridge, the Poliorcetica, and Trajan's Column all outlasted whatever dispute, if any, attended his end.
