Given that the Simon Necronomicon (along with all the others) is a creative work based on hints scattered in Lovecraft, I'd say that one is free to experiment. A parallel case: most of the old Nordic tradition is irretrievably lost. But Stephen Flowers, writing as Edred Thorsson, undertook what he styled a "reconstruction." That is, taking the bits that survived and drawing on his genuine scholarship (a PhD in Germanic Languages), plus lots of experimenting and collating the results of his Rune Gild's adherents, he hammered out what is said to be a workable system of galdry and sedhry.The Simon Necro. A question about the gates also, are we supposed to circle the gates and also have a flour circle around them? Thanks for your answer.
