Celtic and Scandinavian Religions by John MacCulloch

The author compares Celtic mythology and religion with the beliefs of early Scandinavian society. Vikings and Norsemen who raided British shores ruled parts of Britain for centuries. The religion of the Scandinavians was the same as the religious beliefs and practices of their fellow Teutonic and Germanic tribes, and their chief deities and religious rituals were like those of Teutonic people anywhere.
