Apollodoros of Damascus
According to Procopius (op. cit. IV., 6), Apollodonis superintended the works undertaken by Trajan (emperor 97-117 A. D.). These were the Forum of Trajan at Rome, with the basilica and the famous sculptured column, and a gymnasium and odeon at Rome. He built also the bridge which Trajan threw over the Danube. Apollodorus was also employed by Trajan's successor, Hadrian (emperor 117-138), at whose request he composed his Poliorceticus, a work on engines of war. The accepted story of Dion Cassius, that Hadrian was jealous of Apollodorus and murdered him on account of certain criticisms which he made of the emperor's designs for a temple of Venus and Roma at Rome, is discredited by Duruy.
