Singara (Ancient Greek: τὰ Σίγγαρα, tà Síngara; Syriac: ܫܝܓܪ)[1] 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.
[2] Its position south-east of Nisibis was indifferently defined by ancient writers, with Stephanus of Byzantium calling it a city of Arabia "near Edessa" and Ptolemy placing it on the Tigris.
The city was raised by Severus to the status of a Roman colony, as is attested by the legend found on some of the coins minted there during the reign of Gordian III: ΑΥΡ.
It was the scene of a celebrated nocturnal conflict during a siege of the city in 344 by Sassanid King Shapur II, the result of which was so unsatisfactory that both sides claimed the victory.
[6][7][8] Still later, in 359/360, during the reign of Constantius II, it is recorded that it underwent a celebrated siege, and at length was carried by the Persians by storm, though gallantly defended by the townspeople and two legions.
