Gordian III was a Roman emperor who ruled from AD 238 to 244. He was the youngest sole Roman emperor at the age of 13. Throughout his rule, coins were used to establish Gordian III’s legitimacy and fitness to rule. Due to his young age, Gordian III had little military experience with no real position and therefore, deities such as Virtus were a common figure presented on his coin. Gordian III spent most of his reign fighting on the frontier while his father-in-law exercised the authority of the emperor on his behalf. Furia Sabinia Tranquillina (c. AD 225 – aft. 244) was married to Emperor Gordian III. This may have been a politically strategic move to secure ties between the emperor and her father, Timesitheus, who became head of the Praetorian Guard in the same year as the wedding. Gordian III was a popular young emperor, but his glory (and that of Tranquillina) was short-lived, as he died at the tender age of nineteen in battle.
Singara of souuth-east Nisibis, was a strongly fortified post at the northern extremity of Mesopotamia, which for a while, as it appears from coins minted there, was occupied by the Romans as an advanced colony against the Persians. It was the camp of Parthica I legio.
