I think that the work of Milton has some biblical aspect in it but it is not that he is a biblical professor, I can attribute this to the fact that his main aim was to present a poem that was to be about creation and the one to point out the cause of death, marriage and the one to answer so many questions that remain unanswered in today’s world. And hence he bases his story in the genesis story of creation.
Milton’s work though it starts with a biblical orientation, he latter integrate paganism in the poem. The paganism comes out since he employs the use of classical references in the book making him some sort of an artist rather than a biblical scholar since for a biblical scholar, they tend not to mix these two aspect.
