Ostoria gens

The gens Ostoria, occasionally written Hostoria, was a plebeian family at Rome. Members of this gens are first mentioned in the early years of the Empire. Although only a few of them achieved any prominence in the Roman state, many others are known from inscriptions. The most illustrious of the Ostorii was probably Publius Ostorius Scapula, who was consul during the reign of Claudius, and afterward governor of Britain.

Praenomina
The main praenomina of the Ostorii were Quintus, Publius, Marcus, Gaius, and Lucius, which were the five most common names throughout Roman history. Only the first three are known from the family of the Ostorii Scapulae.

Branches and cognomina
The cognomina of the Ostorii occurring in ancient historians were Sabinus and Scapula. Sabinus refers to a Sabine, and typically indicates that the bearer was of Sabine ancestry. Scapula, literally "shoulder-blade", was probably given to someone with prominent shoulders. The Scapulae were the only important family of the Ostorii, holding four consulships over the course of the first century.

Ostorii Scapulae

 * Quintus Ostorius Scapula, appointed by Augustus one of the first two prefects of the Praetorian Guard, in AD 2.
 * Publius Ostorius Scapula, governor of Egypt during the latter part of the reign of Augustus, attested from AD 3 to 10 or 11. He was probably the brother of the praetorian prefect, and father of Publius and Quintus, consuls during the reign of Claudius.
 * Quintus Ostorius (P. f.) Scapula, consul suffectus in AD 41. He was probably the son of the governor of Egypt, but perhaps of the praetorian prefect.
 * Publius Ostorius (P. f.) Scapula, consul suffectus circa AD 45, became governor of Britain the following year. He fought successfully against a number of British tribes, defeating the Silures, and being granted the insignia of a Roman triumph.  He died before leaving office.
 * Marcus Ostorius P. f. Scapula, served in his father's army in Britain, and was commended for his bravery. He was consul suffectus ex kal. Juliis in AD 59.  In the reign of Nero, he refused to support the accusation of maligning the emperor raised against Antistius Sosianus, but in AD 66, Sosianus accused him of conspiring against Nero.  He took his own life before he could be murdered on the emperor's orders.
 * Marcus Ostorius Scapula, consul in AD 98, during the reign of Nerva.
