Design The column shows 2,662 figures and 155 scenes; Trajan himself appears on the column 58 times. The continuous helical frieze winds 23 times from base to capital and was an architectural innovation in its time. The design was adopted by later emperors such as
Marcus Aurelius. The narrative band expands from about at the base of the column to at the top. The scenes unfold continuously. Often a variety of different perspectives are used in the same scene, so that more can be revealed (
e.g., a different angle is used to show men working behind a wall).
Historical content portrayed The relief portrays Trajan's two victorious
military campaigns against the Dacians; the lower half illustrating the first (101–102), and the top half illustrating the second (105–106). These campaigns were contemporary to the time of the column's construction. The frieze repeats standardized scenes of imperial address (
adlocutio), sacrifice (
lustratio), and the army setting out on campaign (
profectio). Scenes of battle are very much a minority on the column; instead it emphasizes images of orderly soldiers carrying out ceremony and construction. The aim of the Dacian campaigns was to incorporate and integrate Dacia into the Roman Empire as a province. On Trajan's Column, imagery related to wartime violence in general seems to have been downplayed and depictions of violent action towards foreign women and children are nonexistent. Key specific events portrayed are the first crossing of the Danube by the Roman legion, Trajan's voyage up the Danube, the surrender of the Dacians at the close of the first war, the great sacrifice by the Danube bridge during the second war, the assault on the Dacian capital, and the death of the Dacian king
Decebalus. The two sections are separated by a personification of
victory writing on a shield flanked on either side by trophies. , a cart-mounted field artillery weapon (relief detail) Great care was taken to distinguish the men and women from both sides of the campaign as well as the ranks within these distinct groups. The scenes are crowded with sailors, soldiers, statesmen and priests, showing about 2,500 figures in all. It also exists as a valuable source of information on Roman and barbarian arms and methods of warfare (such as forts, ships, weapons, etc.) and costume. The relief shows details such as a
ballista or catapult. This detail is evident in the variety of trees on the Column, each individually stylised following 37 types, which has led some scholars to identify particular species. The precise details create a strong effect of
verisimilitude; the designer presents the images as objective historical truth. Women for the most part occupy and define the margins of the scenes. However, mortal females in Roman state art are so rare it is remarkable that they are included at all in a war monument. In the male discourse of warfare, women are a visual trope that develops further the idea of subjugation by feminizing the foreign conquered. However, on the column is "one of the most unusual, disturbing, and violent depictions of women in Roman art, the torture scene." In this unusual scene, four Dacian women are depicted torturing two naked men. ==Setting==
