HERMOGENES: That is very probable, until some more probable notion gets into your head.
SOCRATES: To prevent that, you had better ask what is the derivation of Ares.
HERMOGENES: What is Ares?
SOCRATES: Ares may be called, if you will, from his manhood (arren) and manliness, or if you please, from his hard and unchangeable nature, which is the meaning of arratos: the latter is a derivation in every way appropriate to the God of war.
HERMOGENES: Very true.
SOCRATES: And now, by the Gods, let us have no more of the Gods, for I am afraid of them; ask about anything but them, and thou shalt see how the steeds of Euthyphro can prance.
HERMOGENES: Only one more God! I should like to know about Hermes, of whom I am said not to be a true son. Let us make him out, and then I shall know whether there is any meaning in what Cratylus says.
SOCRATES: I should imagine that the name Hermes has to do with speech, and signifies that he is the interpreter (ermeneus), or messenger, or thief, or liar, or bargainer; all that sort of thing has a great deal to do with language; as I was telling you, the word eirein is expressive of the use of speech, and there is an often-recurring Homeric word emesato, which means “he contrived”—out of these two words, eirein and mesasthai, the legislator formed the name of the God who invented language and speech; and we may imagine him dictating to us the use of this name: “O my friends,” says he to us, “seeing that he is the contriver of tales or speeches, you may rightly call him Eirhemes.” And this has been improved by us, as we think, into Hermes. Iris also appears to have been called from the verb “to tell” (eirein), because she was a messenger.
HERMOGENES: Then I am very sure that Cratylus was quite right in saying that I was no true son of Hermes (Ermogenes), for I am not a good hand at speeches.
SOCRATES: There is also reason, my friend, in Pan being the double-formed son of Hermes.
