Xenophon, [i]Estate manager[/i], Chapter 2, Section 17 wrote:καταμαθὼν γάρ ποτε ἀπὸ τῶν αὐτῶν ἔργων τοὺς μὲν πάνυ ἀπόρους ὄντας, τοὺς δὲ πάνυ πλουσίους, ἀπεθαύμασα, καὶ ἔδοξέ μοι ἄξιον εἶναι ἐπισκέψεως ὅ τι εἴη τοῦτο. καὶ ηὗρον ἐπισκοπῶν πάνυ οἰκείως ταῦτα γιγνόμενα.
Hints:
καταμαθὼν ... ποτε ... ἀπεθαύμασα, καὶ ἔδοξέ μοι - the basic structure here is an aorist participle with these two verbal phrases.
καταμανθάνειν -
observe;
perceive. A step further than the monkey-see-monkey-do of μανθάνειν.
ἔργων - consider also that this could be
possessions (in the sense of them being used for a purpose that could make money -
utilisation of possessions,
industry (
opp.
idleness, not "
industry" in the post-industrial revolution meaning))
ἀπὸ τῶν αὐτῶν ... τοὺς μὲν ..., τοὺς δὲ - ἀπὸ τῶν αὐτῶν ... -> τοὺς μὲν ..., τοὺς δὲ - ἀπὸ is of course "
from", but we are used to emphasising the destination "
leads to" - these accusatives are part of the participial phrase.
ἀποθαυμάζειν -
really wonder a lot
ἄξιον -
worthy of (+ noun in the genitive), but the feeling is much more similar to our
worthwhile to (+verbal equivalent of the noun in the genitive)
ἐπίσκεψις -
investigation,
inquiry. It would be expected that the thing being inquired into would be in the genitive, i.e. the phrase ὅ τι εἴη τοῦτο is NOT the thing inquired into. The thing being inquired into is probably the way that the two groups (the τοὺς μὲν ..., τοὺς δὲ) do the same things (the τῶν αὐτῶν ἔργων) with such different results.
ὅ τι εἴη τοῦτο - this is the process of the inquiry, not the subject or result of it. That is to say that the inquiry expressed by the ἐπίσκεψις is to ask the wh- questions, in this case ὅ τι εἴη τοῦτο (in indirect speech, i.e. τί ἐστιν τοῦτο; in direct speech), what is this thing that leads one groups to dire straits and the other to wealth. [FWIW. The end of the inquiry is expressed by the verb, which comes up in the next phrase, viz. εὑρεῖν. The verbal equivalent of ἐπίσκεψις, ἐπισκοπεῖν is used in the same way by Xenophon of
the question that it is suggested that one should ask oneself after reading the inscription at the Delphic oracle. (i.e. τὶς εἰμί)]
οἰκείως -
in a way that is (really quite)
familiar (to us)
[Sorry, this one's gone and gotten itself a bit wordy-like and explanational. I hope you can distance yourself from the analytical thinking that this will have evoked and still just "read".]
