Reddit mentions of Hekate Liminal Rites: A historical study of the rituals, spells and magic of the Torch-bearing Triple Goddess of the Crossroads (Greek & Anatolian Goddesses)

I found Hekate Liminal Rites to be a really good read. It seemed well researched.

For what it is worth, it may not be a large standing temple. Tributes, sacrifices, and worship of Hekate were done largely outside of a temple context. She is the goddess of the crossroads; which is where many of her ceremonies would have been done, typically under cover of night. You would have also found her likeness on doorways and on crossroads stones. She is a gatekeeper, a cthonic goddess, a guide through darkness - her veneration would not have been done in large temple complexes. If interested in the history of Her worship, read "Hekate Liminal Rites: A historical study of the rituals, spells and magic of the Torch-bearing Triple Goddess of the Crossroads". It gives a good read on historical worship and the Dark Goddess's manifestation.
