Quintus Antonius Isauricus

Quintus Antonius Isauricus was a Roman legatus legionis commanding Legio VI Victrix in Britain during the late AD 140s. He is attested as later serving as suffect consul in May 156 or 157 under Antoninus Pius with Lucius Aurelius Flaccus as his colleague.

Life Anthony Birley makes several comments about Isauricus' name and likely family. Birley notes Quinti Antonii are rare in all parts of the Roman Empire, and only one other senator is known. The cognomen "Isauricus" is reminiscent of two consuls of the late Roman Republic, Publius Servilius Vatia Isauricus, consul 79 BC, and his son Publius Servilius Vatia Isauricus, twice consul in 48 BC and 41 BC; their descendants can be traced into the second century AD. Birley speculates that Antonius Isauricus may be descended from these Republican consuls through the female side.

Quintus Antonius Isauricus is named in an inscription from Eboracum (York). The inscription was dedicated to his wife, Sosia Juncina, whom Birley speculates may have been related to another consul, Quintus Sosius Senecio, consul in 99 and 107. The stone, measuring 71 x 40 x 38 cm and made of limestone, is inscribed with seven lines of texts.

The stone inscription reads: DEAE / FORTUNAE / SOSIA / IUNCINA / Q(uinti) ANTONI / ISAURICI / LEG(ati) AUG(usti) To the Goddess Fortuna, Sosia Juncina, wife of Quintus Antonius Isauricus, Imperial Legate, built this.
