I've tried searching for other threads about pantheons and deities, but this is the closest I could find. A lot of what I've read encourages one to choose a pantheon and work with the gods & goddesses, even if just temporarily. Also, I've been cautioned not to "mix" them (like, using one God from Egyptian mythology and a goddess from Greek culture). In choosing a pantheon, it seems a little confusing to me. My first choice was exploring Celtic mythology (because I am half-Irish) but then it seemed confusing because of the Welsh, Irish, etc. That being said, I was immediately drawn to Rhiannon because of her tale of justice, being a goddess of horses and can be linked to fairies. She also draws her power from animals and nature, and appears as horses and birds.
Cernunnos is my male deity I am drawn to, because he is the Horned God and King of the Forest and animals, he represents cycles and seasons and just seems nice...not intimidating like some others out there.
Sucellus appeals to me as well, representing domesticity and prosperity, and above all, good times (a god who represents beer and libations? Yes please! LOL). He is often with his female partner Nantosuelta, who represents both fertility and re-birth and her symbol animals is a raven, so she is thought to help people cross to the Otherworld (their version of Summerland).
Now trying to figure out what to do with these guys is a different story lol, since I've learned about them and knowing when to call on them and for what.
