I admit it: I chose the title for sensationalism and because it got your attention...which is also why I chose some of those overly dramatic tags. But, really, you want to practice Necromancy? Specifically, Greek Nekromantia? Well, sit tight! I've got a nice, loooong list for you to browse.
(Ahead of time, forgive the chipper tone. I am not making light of the subject...I just haven't slept much tonight.)
Needless to say, there's a lot of preliminary reading and working before you get to the good stuff (well, it's all good stuff, but anyway...). The more experience and knowledge you have, the stronger your foundation for your spiritual temple- the thing you are aiming to become. Because, well, Nekromantia is a serious, spiritual practice with the potential for enrichment just like any other spiritual path.
What, you say? I just wanna make dead people sit up and talk (riiiiiight) and seem dark and mysterious to my friends? Then, no hard feelings. Rest assured, with that attitude at best you will be nothing but a joke to serious practitioners. But hey, that's your choice, right?
You're not a teen, a goth (I mean, goth isn't your only reason for being) or someone with a severe mental illness who is non-lucid? I take no responsibility for you getting yourself into trouble, whomever you are. I highly suggest you read all of these books with a rational, moral view and obey the law where you are. Just because a book told you to do something doesn't mean you have to go out and do it, you know?
So, on to it! A warning- none of these books spell it all out, and you can't learn the real stuff only by reading. Be prepared to figure stuff out on your own from the works of scholars and to learn from experience, and to listen to the gods in your heart. And don't just skip down to the bottom or skip the other books- you'll only be cheating yourself.
Everyone has to start somewhere, and this is a short list of books that will help you get a decent understanding of Greek Religion, the Underworld and the mindset you should be developing.
Greek Religion: Archaic and Classical To flesh out "Old Stones, New Temples". Between these two books, you should have enough to write the necessary rituals and figure out how to please the Underworld gods.
The Greek Way of Death More to flesh out your practice. *hint* Pay attention to the chapter on "Visiting the Tomb".
Good enough? You've gotten all that? Great! On to the next...
Needless to say, even for beginners, working with death energy, the underworld and nekromantia can bring up some pretty heavy personal issues. Thankfully, I have some wonderful resources here that will help you deal with your inner "demons" (I.E., the buried parts of yourself in your unconscious mind) and help you thrive on the dark. There is a lot more to these books than you might think, so read and re-read.
These are books to help focus your intent and to build the skills necessary for this kind of work. The primary skills right now are psychic self-defense, astral projection, dream-walking, incubation and meditation.
Finally here, huh? Have you read all the other books? Have you done the necessary work? Have you read between the lines? If you have, you are probably very changed and have a better idea of who you are and where your skills are. And it probably took you a good, long while. Are you really ready to try it? Only you know for sure. If you are fortified with greater knowledge and skills, then journey on.
Greek and Roman Necromancy Pretty much a how-to manual on the way it was done in the old days. Of course, you're going to have to do some heavy modernizing and reconstructing, as not to violate morality and the law, but that shouldn't be a problem at all. There was stuff done in the ancient world we DEFINITELY should never do now.
