Hmmm,

Astynome and Astykratia are both feminine - they wouldn't
apply to Zeus. Who then? (think, think)

Thank-you everso much,

I knew that Thera, 'Chios' and Ogyia were islands, and that
the mythological persons and ancient names coincide with
some of the present named constellations and planets,

I browsed through Richard H. Allen's *Star Names* which is
about the `ne plus ultra' in that field

100 years ago, maybe. Vast amounts of work on ancient and classical
astronomy have been done since.

and could find no reference
to the names or to Thebes. This is a tough one.

I imagined that there might be some link or other with the 7
gates or names of the daughters (one ref said there were
10 sons also! but I think thats from an earlier in myth)

Yes, Ogyia could also mean "the children of Ogyges".

Alternatively gates to a city are generally an in-bound route
from main roads to/from other main cities, maybe ones lost
to us without archaeological evidence,

Like Sybaris, that the Crotonians utterly destroyed and then
diverted the River Crathis to cover its ruins. The river dried
up over the centuries and the site of Sybaris was discovered
in 1967.
