Summon

perrych manny have found the necronomicon system to work and I am talking about simnon's necronomicon if you would like to disuss it further I would be delighted to discuss it by PMS

I would be inclined to agree with @Perrych on the autenthicy of the Necronmicon, for Simon's Necronomicon strangely enough appeared after H P Lovecraft's version. And then , certain Simon , and Orthodox Christian Priest ( !!! ) presented , his , "real version". The fictional book is based on some Persian and Sumerian myth s but that does not make it real at all. However this is another topic, we should not further discuss here, a new discussion could be started rather, in suited forums section.

Asker inquired about summoning spells not grimoires :)
As to it another example could be weather conjuration.
Asperging rain water using broom, as one chants some words of power is a nice example. Same could be said for pouring water on stone throughout a sieve, or "whistling up" a wind.

What people informally reffer to as "lover spirits" ( elementals, fae, nature spirits ) could be summoned by spells as opposed to summoning rite's , which myself and others have previously described as summoning spells.

Also necromanting spells, invoking the pressence of the dead for divinator y purposes can be seen as summoning spells, and do not require ceremonies and elaborated procedures.

I too am talking about the Sumon Necronomicon and see no reason why we can't discuss it here. The whole thing is a joke. Look at the incantation to summon Yog Sothoth. Then look at the Rabbelini table invocation in the seventh book of Moses. Same thing huh? Which brings up another question. Why would there be latin prayers to the Christian God in an old Sumerian grimoire. Then compare the gate of the moon with the first pentacle of the moon in the GKoS. Same thing again right? Only this time, the names of the archangels have been replaced with Sumerian gods. I haven't read the Sinon Necronomicon for a while but I remember noticing alot of stuff like this.
