Apollodorus of Damascus

Apollodorus of Damascus (Greek: Ἀπολλόδωρος ὁ Δαμασκηνός) was a Syrian-Greek engineer, architect, designer and sculptor from Damascus, Roman Syria, who flourished during the 2nd century AD.

Apollodorus was a favourite of Trajan, for whom he constructed Trajan's Bridge over the Danube, for the 105–106 campaign in Dacia.

He also designed the Forum Trajanum and Trajan's Column within the city of Rome, beside several smaller projects. Apollodorus also designed the triumphal arches of Trajan at Beneventum and Ancona. He is widely credited as the architect of the third iteration of the Pantheon, and cited as the builder of the Alconétar Bridge in Spain. In 106 he also completed or restored the odeon begun in the Campus Martius under Domitian.

Trajan's Column, in the centre of the Forum, is celebrated as being the first triumphal monument of its kind. On the accession of Hadrian, whom he had offended by ridiculing his performances as architect and artist, Apollodorus was banished and, shortly afterwards, being charged with imaginary crimes, put to death. He also wrote a treatise on Siege Engines (Πολιορκητικά), addressed to an unnamed emperor, likely Trajan.

The story about Apollodorus' death demonstrates the persistent hostility felt towards Hadrian in senatorial circles long after his reign, for if Cassius Dio included it in his history, he must have believed it. Many since have taken Dio's anecdote at face value, but there is much in this story that does not add up and many scholars dismiss its historicity altogether.
