Lucius Aelius Seianus (20 BC – October 18, AD 31), commonly known as Sejanus, was an ambitious soldier, friend and confidant of the Roman Emperor Tiberius. An equestrian by birth, Sejanus rose to power as prefect of the Roman imperial bodyguard, known as the Praetorian Guard, of which he was commander from AD 14 until his death in AD 31.

While the Praetorian Guard was formally established under Emperor Augustus, Sejanus introduced a number of reforms which saw the unit evolve beyond a mere bodyguard into a powerful and influential branch of the government involved in public security, civil administration, and ultimately political intercession; changes which would have a lasting impact on the course of the Principate.

During the 20s, Sejanus gradually accumulated power by consolidating his influence over Tiberius and eliminating potential political opponents, including the emperor's son, Drusus Julius Caesar. When Tiberius withdrew to Capri in 26, Sejanus was left in control of the entire state mechanism as de facto ruler of the empire. For a time the most influential and feared citizen of Rome, Sejanus suddenly fell from power in 31, the year his career culminated with the consulship. Amidst suspicions of conspiracy against Tiberius, Sejanus was arrested and executed, along with his followers.

Sir Patrick Stewart, OBE (born 13 July 1940) is an English film, television and stage actor, who has had a distinguished career in theatre and television. He is most widely known for his television and film roles, such as Captain Jean-Luc Picard in Star Trek: The Next Generation and its successor films, Professor Charles Xavier in the X-Men film series, and as the voice of Avery Bullock in American Dad!.

Stewart was born on 13 July 1940 in Mirfield, near Dewsbury in the West Riding of Yorkshire, England.

In a 2008 interview, Stewart said: "My father was a very potent individual, a very powerful man who got what he wanted. It was said that when he strode onto the parade ground, birds stopped singing. It was many, many years before I realised how my father inserted himself into my work. I've grown a moustache for Macbeth. My father didn't have one, but when I looked in the mirror just before I went on stage I saw my father's face staring straight back at me."
