An extensive look at the lore.
Discusses the oldest known lore from the region, the history, the patterns of behavior, and the regional beliefs. All sorts of things -- jinn belong to every religion that humans belong to, and some Muslims use crosses to ward off Christian jinn, and "Passover biscuit" to ward off Jewish ones; Egyptians identifying ghosts as jinn, and having one that exactly matches a description of Set; how jinn fear wolves; and a lot more.
Sometimes draws analogies between jinn and other folklore, but some you just have to know. (The midwife who got the kohl for the baby's eyes on one of her own, and so lost that eye later when she betrayed that she could see jinn.)
Concludes with some literary accounts and modern day tales.
