Happy Twentieth to everyone here!. Lately I have been working on putting together some audio material on Lucretius, and this morning I was following a link to a blog entitled "The Wrong Monkey" which I know absolutely nothing about - except that I have now scanned three blog posts written about Lucretius and Greenblatt's book "The Swerve" about the transmission of the text. I think if you start with the link I will post below and follow back to check his previous two posts, you will find some valuable material about references to Lucretius during the period when it is commonly presumed today that his work had been "lost." The key work cited appears to be a book by David Butterfield: "The Early Textual History of Lucretius" which appears to be well worth checking out.
