“Sejanus: His Fall” is a tragedy play written by Ben Jonson, based on the historical events surrounding the downfall of Lucius Aelius Sejanus, a powerful Roman general who served as the chief advisor to Emperor Tiberius.

The play opens in ancient Rome, where the ambitious Sejanus, the commander of the Praetorian Guard, is plotting to seize power and overthrow Emperor Tiberius. He manipulates and conspires with various members of the Roman court to achieve his goal, including winning the favor of Tiberius’s mother, Antonia, and forming a romantic relationship with Livilla, Tiberius’s niece.

As Sejanus gains power, rumours about his motivations circulate and Tiberius starts to question Sejanus’ loyalty. As the emperor grows more distant from Sejanus, he makes plans to depose him from his position of authority. As the plot against Sejanus is revealed, his rash ambition and thirst for power bring him to his knees. He is detained, put on trial, and ultimately given the death penalty. His accomplices turn on him, and he is put to death.

Throughout the play, Jonson explores themes of ambition, power, and betrayal. “Sejanus: His Fall” serves as a cautionary tale about the dangers of seeking power at any cost and the fragility of political alliances in a society driven by ambition and treachery. The play depicts the corrupting influence of power and the consequences of unchecked ambition in the context of ancient Rome’s political intrigues.
