Socrates. I think it would be clearer if we were to use the Doric form of the name. The Dorians call it Ἅλιος. Now ἅλιος might be derived from collecting (ἁλίζειν) men when he rises, or because he always turns (ἀεὶ εἱλεῖν) about the earth in his course, or because he variegates the products of the earth, for variegate is identical with αἰολλεῖν.

Hermogenes. And what of the moon, Selene?

Socrates. That name appears to put Anaxagoras in an uncomfortable position.

Hermogenes. How so?

Socrates. Why, it seems to have anticipated by many years the recent doctrine of Anaxagoras, that the moon receives its light from the sun.

Hermogenes. How is that?

Socrates.Σέλας (gleam) and φῶς (light) are the same thing.

Hermogenes. Yes.

Socrates. Now the light is always new and old about the moon, if the Anaxagoreans are right; for they say the sun, in its continuous course about the moon, always sheds new light upon it, and the light of the previous month persists.

Hermogenes. Certainly.

Socrates. The moon is often called Σελαναία.

Hermogenes. Certainly.

Socrates. Because it has always a new and old gleam (σέλα νέον τε καὶ ἕνον) the very most fitting name for it would be Σελαενονεοάεια, which has been compressed into Σελαναία.

Hermogenes. That is a regular opera bouffe name, Socrates. But what have you to say of the month (μήν) and the stars?

Socrates. The word month (μείς) would be properly pronounced μείης, from μειοῦσθαι, to grow less, and I think the stars (ἄστερα) get their name from ἀστραπή (lightning). But ἀστραπή, because it turns our eyes upwards (τὰ ὦπα ἀναστρέθει), would be called ἀναστρωπή, which is now pronounced more prettily ἀστραπή.

Hermogenes. And what of πῦρ (fire) and ὕδωρ (water)?

Socrates.Πῦρ is too much for me. It must be that either the muse of Euthyphro has deserted me or this is a very difficult word. Now just note the contrivance I introduce in all cases like this which are too much for me.

Hermogenes. What contrivance?

Socrates. I will tell you. Answer me; can you tell the reason of the word πῦρ?

Hermogenes. Not I, by Zeus.

Socrates. See what I suspect about it. I know that many Greeks, especially those who are subject to the barbarians, have adopted many foreign words.

Hermogenes. What of that?

Socrates. If we should try to demonstrate the fitness of those words in accordance with the Greek language, and not in accordance with the language from which they are derived, you know we should get into trouble.

Hermogenes. Naturally.
