" Satan, the chief devil of the Western World, was originally an angel whose duty it was to report human delinquencies to God. It was not until the Fourteenth Century that he began to be depicted as an evil deity who was part man and part animal, with goat-like horns and hooves. Before Christianity gave him the names of Satan, Lucifer, ect., the carnal side of man's nature was governed by the god which was then called Dionysus, or Pan, depicted as a satyr or faun, by the Greeks. Pan was originally the "good guy" and symbolized fertility and fecundity. "
