The Pantheons Celtic Roman Nordic Gods and Goddesses This section of the website gives a description of the pantheons that have been worshiped in the British Isles, over two millennia. The 'quick guides' within each category give a brief description of the gods in each pantheon. While some of the gods have been expanded upon. We eventually hope to have a comprehensive list with each god or goddess dealt with separately. A depiction of the Celtic/Roman God at Aqua Sullis, Bath in the county of Avon.
