The purpose of the present study is to describe the struggle against paganism and pagan survival in Spain up to the fall of the Visigothic kingdom in 712. By paganism is here meant not only the worship of the pagan gods, but also the practices associated with pagan worship, such as astrology and magic. An attempt will be made to show the part that political, social and religious factors played in pagan survivals as well as to point out the various manifestations of paganism. This study, it is hoped, will throw light upon a phase of early Spanish history that has not hitherto been adequately treated. It will enable the reader to compare the paganism of Spain with that found in Africa, France, Germany and Italy, in as far as the extant sources and modern studies make such comparison possible.
