The apparatuses of this book deal with the linguistic and supralinguistic (poetic) form of the fragments edited in book III.3.B/i.Apparatus IV lists or describes such elements of the Heraclitean language as its dialect, its syntax, its uses (articles, ellipses.), while Apparatus V exhibits the poetic configurations of the various levels of discourse (from the hypophonic [prosodic] level to the semantic level, including the phonic structures [chimes] and the taxic structures [parallelisms, chiasmuses.). Numerous figures and diagramms are added to illustrate and complement the apparatuses.This volume contains in addition the text of a paper intitled 'Pré-texte philosophique ou Pré-philosophie poétique. Le cas Héraclite ' (Lille, 1998)
