Arch of Trajan (Timgad)
|Location||Timgad, Batna, Algeria|
|Type||Roman triumphal arch|
|Completion date||c. 100 AD|
|Dedicated to||Emperor Trajan|
The inscription on the attic records the foundation of the colony on the part of Trajan in the year 100. The decorative fabric of the monument, with the sides of the lateral arches detached from the wall, was taken with a curvilinear pediment that forms two protruding and strongly contrasted lateral aediculae. This and the lavish decoration of the architectural elements, all suggest a later dating.
The arch reaches a height of 12 metres, with a central arch of 6 metres in height which permitted the passage of vehicles that have left deep ruts in the ground under the archway. The lateral arches, each 3.75 metres high, were reserved for pedestrians.
Above the lateral arches on both sides are deep rectangular niches, which are flanked by aediculae with smooth-stemmed Corinthian columns of coloured marble on shelves. The niches were designed to hold statues, which are now lost. The whole assemblage of each lateral arch and niche was framed by two red Corinthian columns, detached from the walls and supported by pedestals. The entablature that runs across the wall above the lateral arches protrudes above the columns, and a curvilinear pediment rests on it in turn. The attic must have been surmounted with a group of monumental statues.
Other sculpture was added to the arch in later times. This includes a statue of the gods Mars and one of Concordia erected under Emperor Septimius Severus by Lucius Licinius Optatianus, on the occasion of his election as flamen-for-life of the colonia.
