Dissertation argument

Hi!

My dissertation for 2nd year English is due in 4 weeks, and I’ve written 4,000 words (5k maximum). My problem is I’m struggling to find a unique argument. My essay is on the Renaissance as a period of mourning of the classical past, an exploration I’ve done through looking at the elegiac poetry of Donne, Philips, Milton, and Jonson.

Anyone have anything interesting that i could research more that could provide this new viewpoint? Thanks!
