I didn’t show all the summoning circles and so forth for the historical spells I listed in the Codex Superno, for a variety of reasons. But for those who are interested here are a couple from the CLM 849, one of the more frankly demonic of the late medieval grimoires.
I can’t hot-link but if you click here you’ll see the magic circle associated with the spell “The Ring of Brimer” from the Superno
