Poetaster (/poʊɪtæstər/), like rhymester or versifier, is a derogatory term applied to bad or inferior poets. Specifically, poetaster has implications of unwarranted pretensions to artistic value. The word was coined in Latin by Erasmus in 1521.[1] It was first used in English by Ben Jonson in his 1600 play Cynthia's Revels;[2] immediately afterwards Jonson chose it as the title of his 1601 play Poetaster. In that play the "poetaster" character is a satire on John Marston, one of Jonson's rivals in the Poetomachia or War of the Theatres.[3]
