Hecate is often seen today as a crone even though in early Greece she was seen as a young maiden.
I think that the crone thing comes from her wisdom, her underworld aspects, and her relation to the practice of magick and I definitely understand it in its *symbolic* sense.
How do people here see Hecate? Crone? Maiden? Or something else?
Most of my research and much of my work with Her has led me to view her as more of a Crone. But it's also entirely possible that I see Her that way because I'm much more comfortable with Crone Goddesses than with any other archetype. And as has been shown many times, Hekate is nothing if She isn't versitile.
It is a bit late, but I just discovered this community, so why not post here anyhow?
In my own personal experiences with Hekate she usually appears to me as the Crone. I think this is because of her associations with death, rebirth, transformation, magical power, wisdom, and prophecy. In modern pagan terms, The Crone is probably where Hekate fits in best. Even though as you so accurately pointed out, she is not depicted that way in ancient sculpture or vases.
There are times I see her differently however. Most recently she appeared to me as a dark woman in her prime. However, she also sometimes appears to me as a corpse with no distinctive features except rotting flesh, or as a grim-reaper-ish figure.
