Recently, I came across a note in one of the books I was reading that listed 'Lucretius, epicurean and poet' in two volumes by John Masson as an important monograph on Lucretius. It got me curious because I've never heard about this author. I tried to find some information about him online and I got even more curious when I found absolutely nothing. I did, however, found the monograph on archive.org along one more book on Lucretius published in 1884 (all the links at the end of this post).
I don't know if the books are worth recommending because I've only skimmed through the tables of contents but at the first look, these works seem to be thorough and interesting studies on Lucretius. If anyone is familiar with these books, please let me know if they are worthwhile.
