This volume analyses in depth the reception of early Greek philosophy in the Epicurean tradition and provides for the first time in scholarship a comprehensive edition, with translation and commentary, of all the Herculanean testimonia to the Presocratics. Among the most significant scientific outcomes, it provides elements for the attribution of an earlier date to the attested tradition of Xenophanes' scepticism; a complete reconstruction of the Epicurean reception of Democritus; a new reconstruction of the testimonia to Nausiphanes' concept of physiologia, Anaxagoras' physics and theology, and Empedocles' epistemology; new texts for better comparing the doxographical sections of Philodemus' On Piety with those of Cicero's On the Nature of the Gods, which update Hermann Diels' treatment of this subject in his Doxographi Graeci.

The papyri transmit a part of the testimonia relevant to pre-Socratic philosophy. The 'Corpus dei Papiri Filosofici' takes this material only partly into account. In this volume, a team of specialists discusses some of the most important papyrological texts that are major instruments for reconstructing pre-Socratic philosophy and doxography. Furthermore, these texts help to increase our knowledge of how pre-Socratic thought - through contributions to physics, cosmology, ethics, ontology, theology, anthropology, hermeneutics, and aesthetics - paved the way for the canonic scientific fields of European culture. More specifically, each paper tackles (published and unpublished) papyrological texts concerning the Orphics, the Milesians, Heraclitus, Empedocles, Anaxagoras, the early Atomists, and the Sophists. For the first time in the field of pre-Socratics studies, several papers are devoted to the Herculanean sources, along with others concerning the Graeco-Egyptian papyri and the Derveni Papyrus.
