Lucius Trebius Germanus was a governor of Roman Britain in 127, and suffect consul with Gaius Calpurnius Flaccus, the proconsul of Cyprus in 123, at an uncertain date.
He is mentioned in the Digest, which cites a legal decision Trebius Germanus made while governor of an unnamed province, not necessarily Roman Britain, condemning a slave boy to death for failing to call for help when his owner was murdered.
[3] Birley speculates on the place of origin for these three consulars, finding less prominent Trebii attested in Italy, Spain, Gaul, and Dalmatia, but preferring none of these.
Birley also suggests that he may be the governor in whose name a broken and now lost inscription found at Bewcastle was made.
[5] Prior to the discovery of this military diploma, Birley had speculated it might have contained the name of the other three governors then attested under Hadrian -- Nepos, Julius Severus, and Mummius Sisenna, or another consular, Gaius Nonius Proculus, who held the consulship in some undetermined nundinium between AD 50 and 150.
