Sejanus His Fall, a 1603 play by Ben Jonson, is a tragedy about Lucius Aelius Sejanus, the favourite of the Roman emperor Tiberius. Sejanus His Fall was performed at court in 1603, and at the Globe Theatre in 1604. The latter performance was a failure. According to Jonson, an unnamed co-author "had good share" in the version of the play as it was "acted on the public stage". For reasons unknown the play was accused of promoting "popery and treason". Jonson was questioned, but no action was taken. Jonson published the play in a revised version, replacing the contributions of his co-author with his own words. The published version was accompanied by copious marginal notes citing its historical sources, in quarto in 1605 and in folio in 1616. Stage history Sejanus His Fall was first performed by the King's Men in 1603, probably at court in the winter of that year. In 1604 it was produced at the Globe Theatre. Contemporary witnesses, including Jonson, reported that the cast was greeted with heckles and hisses by their first audience at the Globe; the 1604 performance was "hissed off the stage". According to Park Honan, the later Roman works of Shakespeare, who had acted in Sejanus, carefully avoided "Sejanuss clotted style, lack of irony, and grinding moral emphasis." The published cast list in Jonson's 1616 folio identifies the principal actors as Richard Burbage, Augustine Phillips, William Sly, John Lowin, William Shakespeare, John Heminges, Henry Condell, and Alexander Cooke (listed in that order). It is not known which parts were played by which actors. David Grote argues that the published list probably mixes two separate productions, as Lowin did not join the King's Men until after the first production. However Grote suggests that the most likely roles for these performers can be identified: Sejanus, the largest role and a classic over-reacher in the Richard III manner, was obviously played by Burbage. The proud Silius, whose confrontation with Tiberius occupies the core of the first three acts and whose suicide is a traditionally noble Roman death, most likely would have gone to Heminges, with the more military Condell as the Guards Captain Macro. Phillips, who had been playing dissolute men for some time, would seem very likely for Tiberius if not for Jonson's hint that it was actually Shakespeare. Still, with Shakespeare as Tiberius, there is a very large role for an indignant speechmaker,
