A survey of religious practices in central and north west Spain in the Iron Age and early Roman periods. The author discusses the literary and archaeological sources for our knowledge of Celtic ritual in this region and then examines the evidence for a range of named gods and goddesses. He discusses the geographical distribution of theonyms, and the rituals practised by the Iberian Celts when these gods were invoked. From human sacrifice to decapitation and the removal of hands, the picture painted is of a bloody and warlike paganism. German text with few pictures.
