What is the primary function of the equestrian statue found in the Forum of Trajan?

The equestrian statue in the Forum of Trajan primarily acts as a victory symbol, celebrating the achievements of Emperor Trajan, particularly his military victories. This statue is emblematic of Roman imperial propaganda that aimed to communicate the strength and success of the emperor to the public. By depicting Trajan on horseback, it not only showcases his valor and command but also reinforces the idea of military triumph as central to the stability and greatness of the Roman Empire. The visual prominence of the statue also acts as a reminder of the power the emperor holds through his military leadership.

While other aspects such as political power may be inferred from the statue's presence in a central public space, the essence of its function is deeply tied to the celebration of victorious accomplishments, making it a symbol of success and glory rather than just a representation of political authority or a religious idol.
