It seems there is a close relation between these two deities.
>Kek and Keket are the raiser of light and the raiser of darkness. Hecate is likewise the bringer of light
>Kek is of the Ogdoad, a primordial group of Gods before the main Gods were on the scene. Hecate is a titan goddess, likewise a primordial set of Gods before the rest of the pantheon was around
>Kek is a god of ambiguity; frogs are beings that straddle land and water. Hecate is likewise ambiguous, being the goddess of crossroads and thresholds.
>One of Hecate's associations is the frog… duh.
Perhaps the Cult of Kek and Witchcraft aren't so different after all?
