Well, the "Anti-" part is unambiguous.
"-ope" however is quite debatable. It can be either from:
1. "ope" meaning "hole"
2. "ope" meaning
- of Place: "by which or what way, in which or what direction"
- of a Manner: "in what way, how, as"
- with other Particles: "in what possible direction or manner" (Liddel &
Scott )
3. "ops" meaning "a poeting noun denoting voice, whether in speaking, shouting, lamenting" (Liddel &
Scott )
4. "opsis" meaning "face", as you mention.
I would (arbitrarily, granted) count out 1 and 3. I would tend to go for 4 (which is the definition you have posted) although I cannot exclude 3 either (which would make
Antiope synonymous to "nonconformist").
Sorry for being incoherent, its a
Monday morning...
