In early
Medieval Aratus Mss. the basic shapes of anicent representations are often preserved:
Luna still has the billowing drapery and a crescent and her torch and her
biga, but now the image is a signifier not a pictorial creation of what her activity suggests.
The same was already true for the 9c Ms of which this one at St.-Bertin is a copy. Behind them is quite certainly an antique Ms, though we don't have it.
For the difference between a picture and a signifier, compare Potator II's
denarius:

Wikipedia:

arc of drapery
still, though, is to suggest that she is moving through the sky.
As for
Artemis being 'illuminating', yes and no. Yes, we have pictures of the torch races at Brauron. No, it is
Luna who corresponds to
Sol and is a Heavenly Body. In the Empire,
Diana got somewhat merged with
Luna /
Selene. But
Artemis, huntress and Ephesian great goddess, was not, I think, merged with the moon. Ancient deities, under the cultural pressure to understand each others' deities in terms of one's own,
had long since syncretized and hyphenated (Zeus-Ammon, Hades-Serapis, etc.) their gods, yet though they overlapped, sometimes marginally, sometimes almost wholly, they are not the same, and often
had quite different roots. The inevitable blurring sometimes challenges our
writing catalogue entries for coins.
The
Artemis who is confuted with
Hekate is not exactly the same
Artemis as the one in stories and cults where there was no such confutation.

Now, yes, I'll move this
thread to Classical Num., because it has bearing on lots of stuff.
