Do we have any evidence that vikings revered or worshiped Loki? I know that Christianity had some influence on the depiction of Norse gods, turning Loki into a Satan-like figure, but is this really the case? If he was worshiped how was this justified considering Loki's role in Ragnarok?
To the best of my knowledge there is no evidence that Loki was ever worshipped, neither in written sources nor in Archeology. Which is not necessarily a surprise - he would not be the only god mentioned that does not appear to have been worshipped.
