If she is she isn’t a very good one. You can generally tell when a writer has a solid grasp of the occult and magic and she just doesn’t display any of that. She is a fantasist, and not great at that either. Or maybe she is an excellent occultist and just doesn’t do any of it in her writing. She exhibits very static, very materialist thinking though so I don’t think so.

I’m not familiar with Liungman’s dictionary, and going by those quotes I don’t think I am missing out. He seems to just list all the meanings he has heard or imagined. Maybe it’s of use to an academic who wants to know what a certain mark could mean but I don’t think it has much use to the practitioner. Analysing a sigil this way is entirely useless.
