Hello
I once read, but I cannot remember where, that aristo-cracy (the rule of the best ones) is related to earth in this way:
"aristos" is Greek for "the best ones" but it allegedly comes from "ar" which means "earth". This would suggest that the "best ones" were the owners of the land. But again I'm not sure if this etymology is correct. Si non è vero è ben trovato...
I've never heard this supposition before, nor do I know of any thema
ar = earth. This is not to say that such a connection doesn't exist, but I've never met it, and my own inclinations are to remain highly suspicious.
More commonly, we say that
ἄριστος (aristos) develops from
Ἄρης (Ares), the god of war, and metaphorically "war" itself. Thus, those on the battlefield who were "most warlike" were also the most "virtuous" or "good."
The thema "Ar" in the name
Ἄρης gave birth to
ἀρετή (arete) -- which means "goodness" / "virtue." And, in turn,
ἄριστος. I'm not actually sure which words preceded which, nor which directly spawned the next.
All of these words, actually, come from the Indo-European thema "AR" which means "to fit; to match." Think of the verbs
ἁρμόζω ("to fit; to be proper"),
ἀρετῶ ("to be proper; to excell") or
ἀραρίσκω ("to join together; to fasten"), whence the noun
άρθρον ("joint; knuckle").
So
ἀριστος is the most fitting, the most proper, the most "virtuous." Nothing to do with the landed class, at least from an etymological standpoint.
You can also find this thema in Latin. Think of
artus (limb) or
ars (craft; art).
Sorry for this interjection; I realize that, ostensibly, it has little to do with the subject of the thread.

No need to apologize. Whatever it takes to explain why you think that an explanation is wrong is on-topic.
