Charles Godfrey Leland - Gypsy Sorcery
The Gypsies, who call themselves Rom or Romany, are a nomadic culture that originated in India during the Middle Ages. They migrated widely, particularly to Europe, where they worked as farm laborers, metalworkers, scrap dealers, and horsetraders. They also made a living as entertainers, fortune tellers, and grifters. Persecuted by the Nazis, and discriminated against to this day, the Rom has a long tradition of magic and shamanism. As Leland points out, these practices have parallels with those of other traditional pagan cultures around the world.
This book discusses spells, incantations, and talismans used within Rom culture, as well as the more practical magic they use in their interaction with the Gorgios--the non-Gypsies. It is this latter topic which provides some of the most interesting and instructional reading. Leland gives some generalized methods of fortune-telling which any prospective psychic would do well to study; as well as the details of the 'Great Secret', a magic trick in which all of your money disappears.
