The extraordinary overall textual situation of Parmenides’ B1,1-3, due to complex, variegate and polymorphous causes, entailed and still entails diverse sorts of problematic issues so to constitute a true labyrinth of philological, hermeneutical and theoretical instances interwoven each other in almost inextricable way. In this analysis, a first substantial knot of philological type resulted necessary to a preliminary discrimination for making sure the textual reconstruction in order to argue then its most literarily clear and specifiable meaning. In this way it (...) was also possible to make sure its semantic and theoretical relevancies. This research leaded to outline and, hopefully, to demonstrate no textual corruption and following misunderstanding happened before sec. XIII, namely corresponding to the lecture present in the first available manuscript, the so-called cod. N, universally excluded and entirely misevaluated, even discarded; instead it is not only the principle, but the unique reliable codex. The detailed analyse including the autoptic exam is the result of enlightening the absolute goodness of this version and the reasons both philological and hermeneutical comparations, which allow to achieve its complete textual rehabilitation and so to grasp its real conceptual content.
