The translations that I shared in the Epicurean Politics thread came from the Transactions of the Connecticut Academy of Arts and Sciences, Volume 23, September 1920. (Given those parts of the text are just Philodemus speaking, and do not quote or mention Epicurus, I do not expect them to be Usener. )
