The main topic of the paper is a problem of locative sense of Parmenidean 'esti' - 'is' in frg. 8 and other places. The question whether being in Parmenides' poem is spherical, and in result, spatial is one of the most 'pregnant' questions in the investigations of the Pre-Socratic philosophy before and after this Father of Ontology. The author is analyzing the use of metaphors in Parmenides and Heraclitus from the Aristotelian point of view (Po. 1457 b 25-33) in order to prove that sphere of being in frg. 8.43 in comparison with line 1.29 about 'well-rounded Truth' is only an antilocative metaphor (cf. frg.5). He is examining many different interpretations of old and contemporary authors and textual testimonies of Simplicius. He is also analyzing pro et contra arguments. The conclusion might also serve as an premise in old controversy of modern semantics about primary locative presupposition of existential constructions in many languages, especially IE (Lyons, Kahn) - maybe in all of them.
