You are right; I've seen nothing quite like this from Nicaea; what she's holding looks more like a globe than a
dish, and she seems to have something there on her back too. Perhaps it's Aphrodite with
Eros and
apple *, or else Peace-Eirene with
Ploutos; the fit isn't perfect with either, but it is a start.
* There's an oddly close fit with the
Venus Verticordia featured on some
Republican denarii (though that one holds a
scale not a globe) and in other respects with the draped Aphrodite found on certain Caesarean coins minted for
Julia Domna. By the way, who knows why those coins stopped showing up on a
CoinArchives search? Don't tell me there's another hacked website!
