In the final scene of Poetaster; or, The Arraignment, Ben Jonson ridicules the language of his fellow-dramatist John Marston. The principal ‘poetaster’ of Jonson’s title is Rufus Laberius Crispinus and it is through the character of Crispinus that Jonson prosecutes his satire. The culmination of Jonson’s lampoon occurs as Crispinus is given purging pills that make him regurgitate various indigestible words and phrases. Many of these have been traced to Marston’s satires and his early plays, sometimes in a heightened form. 1 Others have not.
