Here's an article (unfortunately not fully readable) on Lucy Hutchinson:
Lucy and Lucretius | History Today
I am really not familiar with the Puritan period and Cromwell, but in closing out DeWitt's book I note that he focused on this time as the end or submergence of a period of interest in Epicurus.
Probably there is a lot of interest in the works of that period and if we eventually develop enough material on it maybe we should have a subforum on Epicurus vs The Puritans.
