Hence before strangers are allowed to enter a ­ district, or at least before they are permitted to mingle freely with the inhabitants, certain ceremonies are often performed by the natives of the country for the purpose of disarming the strangers of their magical powers, or of disinfecting, so to speak, the tainted atmosphere by which they are supposed to be surrounded. —The Golden Bough, Sir James George Frazer Learn...
