Isis – image source unknown
A witch friend recently turned me back on to the Fellowship of Isis which was co-founded by Olivia Robertson and her brother Lawrence and his wife Pamela from 1976. Here is their website (which has lots of other videos, wave files, pictures, and downloadable liturgy) and blog and a video below previewing their DVD on Olivia as the Priestess of Isis, though they worship many god/esses and are open to all faiths there. It is still my opinion that ISIS is the primal Goddess of the western hermetic and magickal systems that sprung from around the Mediterranean and southern Europe, basically anywhere the Greeks and Romans took her knowledge and worship.
Olivia must be around 96 years of age now, though of late she has been in hospital with a broken ankle. Her spirit in this video reminds me of my elder High Priestess in our Coven of the Catta, Lady Alsace. May they both continue to live long fruitful lives until the Goddess calls them home!
