The seal or sigil of lucifer that is floating around seems to be from the Grimorium verum.
Can anyone confirm that this is really the best seal to use? Grimorium verum has been criticized by many people as not being really authentic.
Is it true that the seal is "probably derived from an earlier work, most likely drawn from a magic square whose origins are now lost"

Basically I am going to evoke lucifer, so I am looking for his PROPER SEAL. I am sorta Luciferarian and LHP.
