But anyway, before I got distracted by my last post.
I wanted to share some things I've learned about Her.
1) She is The Unseen Witness. This is an epithet I personally have given Her, but which derives from Her role as Persephone's savior and guide to and from the underworld.
2) She's pre-Greek. Anatolian, actually. That's how I personally like my deities—from a localized cult but so powerful they got picked up by a nearby pantheon (Diana is another example of this).
3) She's a goddess that was traditionally worshiped not in temples, but at homes. In my personal experience, She has a LOT of presence in apartments and shelters (especially shelters), as they are inherently liminal living situations.
4) She presides over Dogs and Polecats (like a weasel or ferret) and Horses, so I view Her as a goddess with dominion over all domesticated pets.
5) Hekate faces the three directions the roads lead at a Y- or T-junction, so in my personal practice I understand The Horned God to stand at Hekate's back and watch The Wild Way for Her. On my altar I have my representation of The Horned God facing away from me. Hekate did call me a sneak for that one, though, so YMMV.
6) I get the vibe she doesn't like to share altar space so she'll be getting a bookshelf of her own soon. You can use keys, the triple moon, and various momento mori (like bones, or the charm I made with a sprig of dead rosemary and a beetle carcass) to represent her in an altar space.
7) Herbs and Plants: Garlic, Yew, Mandrake, Dandelion, Belladonna, Cyclamen, Hemlock, Mint, Oak, Date Palms, Willow, Wolf's Bane. You'll notice many plants in her domain are poisonous or otherwise baneful. To this extent, she presides over all baneful plants.
8) She basically requires you to prioritize self-improvement and learning. Therapy and working out and reading and journaling can all be devoted to Her.
9) UPG but I also associate Her with mushrooms, moths, foxes, and rose thorns. She is carrion birds and the rust that eats at iron. She is the dark side of the moon and She likes it that way.
