Allusions to a cosmogony contained in a Vedic hymn present striking analogies to a cosmogony attributed to the Pythagoreans by Aristotle, Simplicius and Stobaeus. The aim of the paper is to evaluate the extent to which they are similar and to which their differences respond to different cultural premises.

In the analysis of Anaxagoras’ physics in view of the relation between his teachings on multitude and heterogeneity, two central questions emerge: 1) How can the structure of the universe considered purely mereo-topologically help us explain that at the first cosmic stage no qualitative difference is manifest in spite of the fact that the entire qualitative heterogeneity is supposedly already present there? 2) How can heterogeneity become manifest at the second stage, resulting from the noûs intervention, if according to fragment (...) B 6 such a possibility requires the existence of “the smallest”, while according to the general principle stated in fragment B 3 there is not “the smallest” but always only “a smaller”? This paper showcases the perplexity of these two questions but deals only with the former. The answer follows from Anaxagoras’ being a thoroughgoing infinitist in the way in which no Greek physicist was: the principle of space isotropy operative in geometry is extended to physics as well. So any two parts of the original mixture are similar to each other not only in view of the smaller-larger relation but also because each contains everything that the other one contains. This in effect means that at the stage of maximal possible heterogeneity each part of any part contains infinitely many heterogeneous parts of any kind whatsoever. So, neither can there be homogeneous parts in view of any qualitative property, nor can there be predominance in quantity of parts of any kind that would make some property manifest. (shrink)

I shall tell you the story, propose an overview, and show the structure, goal, and peculiarities of this monstrous edition that I undertook forty-four years ago: the Heraclitea, of which ten volumes have appeared since 1999. One volume was published in November 2011 and a few others are still in preparation. While telling you this story, I shall strive to show the radical differences between my approaches and the standard ones taught worldwide in the departments of classics and ancient philosophy (...) in universities.

Reports of lunar and solar eclipses are of interest to students of both history and the history of science. Used with care, they can anchor significant historical events in time. Greek literature, like that of other civilizations, has its fair share of such reports. Often they motivate the actions of characters or expose aspects of belief. Sometimes they shed light on the assumptions of the writer. There are three places in theHistoriesof Herodotus where the author mentions darkenings of the sky (...) (generally taken to be solar eclipses), which have narrative significance and which assist in dating the wars between the Lydians and the Medes (1.74) and between the Greeks and the Persians (7.37 and 9.10).
