Overview
Lucius Seius Strabo (46 BCafter 16 AD) was a prefect of the Roman imperial bodyguard, known as the Praetorian Guard, during the rule of the emperors Augustus and Tiberius. The length of Strabo's tenure as Praetorian prefect is unknown, but he held the position together with various colleagues until 15, after which he was appointed to the governorship of Egypt. With this career Strabo distinguished himself by attaining the two highest offices open to men of the equestrian class in the Roman Empire.
His son was Lucius Aelius Sejanus, who succeeded his father as Praetorian prefect in 15, and gained great influence under Emperor Tiberius before dramatically falling from power in 31.
Family
Lucius Seius Strabo was born around 46 BC in Volsinii, Etruria, to the family of Marcus Seius Strabo and Terentia. Although the Seii were Romans of the equestrian class, Strabo's father maintained relations with senatorial families through his marriage with Terentia. Her brother was Aulus Terentius Varro Murena, who shared the consulship with Augustus in 23 BC, and her sister, a more well known Terentia, was the wife of Augustus' political ally Maecenas.
