A successful imperial candidate for the post of quaestor provinciae early in his career, he was later appointed either curator rei publicae of Aquinum or Urvinum Mataurense.
In around AD 185, Terentianus was possibly the Legatus and Iuridicus of Hispania Citerior.
Finally, sometime around 193, he was appointed suffect consul, by one of the reigning emperors (Commodus, Pertinax, Didius Julianus or Septimius Severus).
[2] It is possible that Terentianus was the Bassus who was reported as an amicus Severi (or friend of the emperor Septimius Severus).
Less likely, he may also have been the Bassus who was Praefectus urbi of Rome for a few weeks during the reign of Didius Julianus.
