This article discusses a not well-known funerary monument commemorating a centurion of British descent. IGLS 13.1.9188 records the centurion, T. Quintius Petrullus, ‘from Britain’, of the Third Cyrenaican Legion, who died aged 30 at Bostra in Arabia. This was a young age for a centurion and the article suggests that he had entered the army by a direct commission rather than risen through the ranks. Accordingly, he is likely to have belonged to a high-status family. The Bostra appointment was probably his first. The appointment is put into context alongside other similar equestrian career paths and the Jewish War during the reign of Hadrian is proposed as a possible occasion for the posting. In addition, the article examines this Briton alongside other Britons abroad.
