This year was published a new book on epicurean political philosophy: "Theory and Practice in Epicurean Political Philosophy. Security, justice and tranquility" by Javier Aoiz & Marcelo Boeri
"The opponents of Epicureanism in antiquity, including Cicero, Plutarch and Lactantius, succeeded in establishing a famous cliché: the theoretical and practical disinterest of Epicurus and the Epicureans in political communities. However, this anti-Epicurean literature did not provide considerations of Epicurean political theory or the testimonies about Epicurean lifestyle. The purpose of this book is to shed light on the contribution of Epicurean thought to political life in the ancient world.
Incorporating the most up-to-date material, including papyri which have been recovered from Herculaneum, documents of Greek epigraphy and the prosopography of the Roman Epicureans, this volume will bring to the foreground new testimonies surrounding the public activities of the Epicureans. In this way, the reader will learn that Epicurean political theory is, in fact, a crucial ingredient of its philosophy. As a result, this connection creates an ongoing dialogue with the Greek philosophical tradition, revealing the presence of Plato in the Epicurean philosophy."
They are latin-american prominent researchers in Ancient philosophy. I think Aoiz has worked on Aristotle and Boeri on the Stoics (I suppose this fact suggests a possible bias, but it can be interesting to see what they have to say on this topic).
