John Milton daringly attempted cosmic themes in regard to the lives and destiny of man, which in itself was a bold change from the old themes. The old themes in English Poetry and poetry elsewhere centred on themes consisting of heroic acts of kings, knights, demons and angels. Milton brought theme to the life of the lowly man and his indebtedness to his creator.It is true that whoever reads and sings his Paradise Lost will begin to think on similar lines and begin to write poems with the same words, tune and imagery, which was exactly what happened in his times.
Thus John Milton pivoted the old style of writing in English Poetry to what is more good, popular and practical.
