1. Sopdet is Sah’s consort and we have already tied Sah to Reusre;
2. In one of the scenes, Reusre is outside Ruddjedet house standing with his kilt upside down. I think this is a reference to looking to the north or possibly laying down and looking straight up;
3. Since Isis, Heqet etc are already involved in the birth as musicians.
I was looking to link to Demeter only to strengthen the link to Sopdet. The one thing that’s not there is the purification of 14 days if it were Sirius which was known to have a purification of 70 days in ancient Egyptian times. 70 is a multiple of 14 but there is no hint that I’ve found of a reason to multiply it.
What are your reasons for tying this to Virgo?
