HERAKLEITOS OF EPHESOS
149

to take the word in the sense it usually bears elsewhere, that, namely, of hurricane accompanied by a fiery waterspout.[1] Yet surely this is just what is wanted. It is amply attested that Herakleitos explained the rise of the sea to fire by means of the bright evaporations; and we want a similar meteorological explanation of the passing of fire back into sea. We want, in fact, something which will stand equally for the smoke produced by the burning of the sun and for the immediate stage between fire and water. What could serve the turn better than a fiery waterspout? It sufficiently resembles smoke to be accounted for as the product of the sun's combustion, and it certainly comes down in the form of water. And this interpretation becomes practically certain when taken in connexion with the report of Aetios as to the Herakleitean theory of πρηστῆρες. They were due, we are told, "to the kindling and extinction of clouds."[2] In other words, the bright vapour, after kindling in the bowl of the sun and going out again, reappears as the dark fiery storm-cloud, and so passes once more into sea. At the next stage we find water continually passing into earth. We are already familiar with this idea (§10). Turning to the "upward path," we find that the earth is liquefied in the same proportion as the sea becomes earth, so that the sea is still "measured by the same tale" (fr. 23). Half of it is earth and half of it is πρηστήρ (fr. 21). This must mean that, at any given moment, half of the sea is taking the downward path, and has just been fiery storm-cloud, while half of it is going up, and has just been earth. In proportion as the sea is increased by rain, water passes

  1. This was written in 1890. In his Herakleitos von Ephesos (1901) Diels takes it as I did, rendering Glutwind. Cf. Herod, vii. 42, and Lucretius vi. 424. Seneca (Q.N. ii. 56) calls it igneus turbo. The opinions of early philosophers on these phenomena are collected in Aetios iii. 3. The πρηστήρ of Anaximander (Chap. I. p. 68, n. 2) is a different thing. Greek sailors probably named the meteorological phenomena after the familiar bellows of the smith.
