Leland's Aradia is not recommended for newcomers. It contains information on various rites that are conducted in the nude, and also mentions the name Lucifer which can be very easily confused with another character by that same name used by monotheists. Quoting from p. 104 in the appendix, "Prominent in this, and naturally enough, was the worship of Diana the protectress - for the alleged adoration of Satan was a far later invention of the Church, and it has never really found a leading place in Italian witchcraft to this day."
This book is often referred to as the pretext for Leland's Etruscan Roman Remains which is said to be a followup to this work. Use this work with caution, and be mindful of the threefold law if you attempt to use any of the incantations; namely the ones outlined in chapters 4 & 5. This book is not recomended for children.
I have been a witch over 13 years and I am a big fan of Charles Leland. This book I am not. It has very little truth to it. Mr. Leland got the text from someone who wanted to abuse the craft with lies. This is a Christian book. That is put in a way to please the church. Witches do not belive in satan, though to this book. The horned god is satan himself. Aradia is said to make comments that would have gotten her killed on the spot. I NEVER threaten the goddess. Again we have many areas saying we do this. There is not enough room to go through it all. You can get free copies from websites all over if you must read it. If you do think about what it is saying and you can easy see it for what it is. A preverted vesion of what should of been sacred.
