The seventeen contributions constituting this edited volume focus on archaic Greek thought -- Presocratics broadly understood, including Sophists, Archaic poets, or Tragedians -- and its multiform reception, use or appropriation through times and lands. The first chapters deal with the direct reconstruction and understanding of early Greek thought, from the very first philosophical writings to the last Presocratic philosopher. By alternating discussions of editorial and translation issues, stylistic analysis, geographical study and history of science, these contributions question the value of the testimonies or fragments attributed to those early thinkers and challenge our understanding of the texts at the origin of western philosophy. The volume subsequently focuses on the echoes of those Archaic voices, over a long period of time from Aristotle to the 20th century. From their early reception in Greek and Roman time to their adaptation in contemporary poetry, by way of their appropriation and use in Islamic philosophy or in Latin-America colonization, the contributions gathered in this second part illustrate the large scope of influence of ancient philosophers and of their ideas in various times and places.
