The Column of Marcus Aurelius (Columna Centenaria Divorum Marci et Faustinae, Colonna di Marco Aurelio) is a Roman victory column in Piazza Colonna, Rome, Italy. It is a Doric column featuring a spiral relief: it was built in honour of Roman emperor Marcus Aurelius and modeled on Trajan's Column. Because the original dedicatory inscription has been destroyed, it is not known whether it was built during the emperor's reign (on the occasion of the triumph over the Marcomanni, Quadi and Sarmatians in the year 176) or after his death in 180; however, an inscription found in the vicinity attests that the column was completed by 193. In terms of the topography of ancient Rome, the column stood on the north part of the Campus Martius, in the centre of a square. This square was either between the temple of Hadrian (probably the Hadrianeum) and the temple of Marcus Aurelius (dedicated by his son Commodus, of which nothing now remains – it was probably on the site of Palazzo Wedekind), or within the latter's sacred precinct, of which nothing remains. Nearby is the site where the emperor's cremation occurred. The column's shaft is high, on a high base, which in turn originally stood on a high platform – the column in total is About 3 metres of the base have been below ground level since the 1589 restoration. The column consists of 27 or 28 blocks of Carrara marble, each of diameter, hollowed out while still at the quarry for a stairway of 190–200 steps within the column up to a platform at the top. Just as with Trajan's Column, this stairway is illuminated through narrow slits into the relief. The spiral picture relief tells the story of Marcus Aurelius' Danubian or Marcomannic wars, waged by him from 166 to his death. The story begins with the army crossing the river Danube, probably at Carnuntum. A Victory separates the accounts of two expeditions. The exact chronology of the events is disputed; however, the latest theory states that the expeditions against the Marcomanni and Quadi in the years 172 and 173 are in the lower half and the successes of the emperor over the Sarmatians in the years 174 and 175 in the upper half.
