I will try to tell you what I think about it;
for no single name could more aptly indicate the four functions of the god, touching upon them all and in a manner declaring his power in music, prophecy, medicine, and archery.
Go on; you seem to imply that it is a remarkable name.
His name and nature are in harmony; you see he is a musical god. For in the first place, purification and purgations used in medicine and in soothsaying, and fumigations with medicinal and magic drugs,
and the baths and sprinklings connected with that sort of thing all have the single function of making a man pure in body and soul, do they not?
Certainly.
But this is the god who purifies and washes away (ἀπαλοούων) and delivers (ἀπολύων) from such evils, is he not?
Certainly.
With reference, then, to his acts of delivering and his washings,
as being the physician of such diseases, he might properly be called Apoluon (ἀπαλούων, the washer), and with reference to soothsaying and truth and simplicity—for the two are identical—he might most properly be called by the name the Thessalians use; for all Thessalians call the god Aplun. And because he is always by his archery controller of darts (βολῶν) he is ever darting (ἀεὶ βάλλων). And with reference to music we have to understand that alpha often signifies together, and here it denotes moving together in the heavens about the poles, as we call them, and harmony in song,
which is called concord; for, as the ingenious musicians and astronomers tell us, all these things move together by a kind of harmony. And this god directs the harmony, making them all move together, among both gods and men; and so, just as we call the ὁμοκέλευθον (him who accompanies), and ὁμόκοιτιν (bedfellow), by changing the ὁμο to alpha, ἀκόλουθον and ἄκοιτιν, so also we called him Apollo who was Homopolo,
and the second lambda was inserted, because without it the name sounded of disaster (ἀπολῶ, ἀπόλωλα, etc.).
Even as it is, some have a suspicion of this, because they do not properly regard the force of the name, and therefore they fear it, thinking that it denotes some kind of ruin. But in fact, as was said,
the name touches upon all the qualities of the god, as simple, ever-darting, purifying, and accompanying. The Muses and music in general are named, apparently, from μῶσθαι, searching, and philosophy; and Leto from her gentleness, because whatever is asked of her, she is willing (ἐθελήμων). But perhaps her name is Letho, as she is called by many foreigners; and those who call her by that name seem to do so
on account of the mild and gentle (λεῖον, Ληθώ) kindness of her character. Artemis appears to get her name from her healthy (ἀρτεμές) and well-ordered nature, and her love of virginity; or perhaps he who named her meant that she is learned in virtue (ἀρετή), or possibly, too, that she hates sexual intercourse (ἄροτον μισεῖ) of man and woman; or he who gave the goddess her name may have given it for any or all of these reasons.
What of Dionysus and Aphrodite?
You ask great things of me, son of Hipponicus. You see there is both a serious and a facetious account of the form
of the name of these deities. You will have to ask others for the serious one; but there is nothing to hinder my giving you the facetious account, for the gods also have a sense of humor. Dionysus, the giver (διδούς) of wine (οἶνος), might be called in jest Didoinysus, and wine, because it makes most drinkers think (οἴεσθαι) they have wit (νοῦς) when they have not, might very justly be called Oeonus (οἰόνους). As for Aphrodite, we need not oppose Hesiod; we can accept his derivation of the name
from her birth out of the foam (ἀφροῦ).
But surely you, as an Athenian, will not forget Athena, nor Hephaestus and Ares.
That is not likely.
No.
It is easy to tell the reason of one of her two names.
What name?
We call her Pallas, you know.
Yes, of course.
Those of us are right, I fancy,
who think this name is derived from armed dances, for lifting oneself or anything else from the ground or
in the hands is called shaking (πάλλειν) and being shaken, or dancing and being danced.
