The term poetaster, meaning an inferior poet with pretensions to artistic value, had been coined by Erasmus in 1521. It was used by Jonson in 1600 and then popularised with this play a year later. Poetaster is a late Elizabethan satirical comedy written by Ben Jonson that was first performed in 1601. The play formed one element in the back-and-forth exchange between Jonson and his rivals John Marston and Thomas Dekker in the so-called Poetomachia or War of the Theatres of 1599–1601.
Benjamin Jonson (c. 11 June 1572 – c. 16 August 1637 was an English playwright and poet. Jonson's artistry exerted a lasting influence upon English poetry and stage comedy. He popularised the comedy of humours; he is best known for the satirical plays Every Man in His Humour (1598), Volpone, or The Fox (c. 1606), The Alchemist (1610) and Bartholomew Fair (1614) and for his lyric and epigrammatic poetry. He is generally regarded as the second most important English dramatist, after William Shakespeare.
