1911 Encyclopædia Britannica/Apollodorus (of Damascus)
APOLLODORUS, of Damascus, a famous Greek architect, who flourished during the 2nd century a.d. He was a favourite of Trajan, for whom he constructed the stone bridge over the Danube (a.d. 104–105). He also planned a gymnasium, a college, public baths, the Odeum and the Forum Trajanum, within the city of Rome; and the triumphal arches at Beneventum and Ancona. The Trajan column in the centre of the Forum is celebrated as being the first triumphal monument of the 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 (Dio Cassius lxix. 4). He also wrote a treatise on Siege Engines (Πολιορκητικά), which was dedicated to Hadrian.
