First, before you say I know about Goddess Hecate and I am not asking about her.
I want to know if their is any path based on Greek Mythology like Wicca, Pegan etc.
If so, what does it called? And where can I find free pdfs on this path?
People who follow the Greek deities will usually put "Hellenic" before whatever religious identification they go by. Like Hellenic Wiccan, Hellenic Pagan, etc.
Well there are the reconstructionists. Some Wiccans generally use some of the practises of ancient rome and greece, which I'm sure you'll find if you look hard enough. There is a great book I'd recommend which may help set you on the way, which is called classical living. I can't remember the authors name, but she is an archeologist who is quiet knowledgeable about their practises and uses them in her own.
First off, Hekate is a Titaness. New Agey people have twisted Her around and named Her a Goddess, which isn't true.
There are reconstructionists. Basically people who do their own thing on their own time. Most of the time Greeky people (like me) call themselves Hellenes, or, more popularly: Hellenic Polytheists. That's the general term, of course, but when you get into the nitty gritty of one's individual specific path, it gets a lot more complicated. Because honestly I don't see another Omni-theistic Eclectic Hellene out there (that's what my "full" title is).
There are mainly books on the path. One I recommend is called Hellenic Polytheism: Household Worship.
But if you're willing to start on the path, I'd be more than happy to help you on your way. :)
Hamilton's mythology is the only book about greek mytholgoy which I know it can be found on pdf.
Theoi is also a good site about mythology and wonderful with a lot of stories about all greek deities,creatures,heroes and so on.
As a little advice,you must understand that deties can accept you but They aren't forced to work with you.So They can be verry different for everyone.Also don't try to find one of them superior to another,they can be very selfish and jealous.
