Final answer:
The epic poem 'Paradise Lost' by John Milton is written in the form of blank verse, which is unrhymed iambic pentameter.
Step-by-step explanation:
The poetic form in which the epic poem Paradise Lost is written is called blank verse. Blank verse is a type of poetry that is quite common for epic poetry. It is characterized by lines written in iambic pentameter, which is a metrical pattern consisting of five iambic feet per line, with each foot containing an unstressed syllable followed by a stressed syllable. This form traditionally does not have end rhymes. John Milton's Paradise Lost is written in this unrhymed iambic pentameter, making it an outstanding example of an epic poem in blank verse.
