The Celtic peoples had many gods of war, if the number linked to Mars is anything to go by. They also had a lot of war-goddesses, whom we would expect to be associated with Minerva, Bellona or Victoria.
Surprisingly, goddesses paired with Victoria are pretty rare (I will look at Minerva in another post), although there are a few. There are also some native goddesses named “Victory”, all from modern France.
When you consider what Hercules did for Gaul, it’s no wonder that they loved him. He founded the city of Alesia, and introduced the rule of law. “And for the entire period from the days of Heracles this city remained free and was never sacked until our own time…”1 (Diodorus Siculus 4.19.1)
Other myths said that Hercules was the father of Celtos, Galatos and Iberus, the ancestors of the Celts, Galatians and Iberians. This would make him the ancestor of the French, Spanish and Anatolian Celts, who would thus become many-times-grand-children of Jupiter.
To honour their fore-father, they offered statuettes of him at shrines (especially the god Borvo’s), and many Gaulish gods, including Ogmios and Smertrios, were paired with him as part of interpretatio celtica. (MacKillop: 248)
Nemetona, Goddess of the Sacred Grove, had her cult in those dense Germanic forests that the Romans feared so much. Especially after the disaster in 9 CE, when three Roman legions and their auxillaries were ambushed and cut down in the Battle of the Teutoburg Forest, they preferred open spaces to the forests in which the druids and others worshipped.
Ancamna was a protector goddess of the Treveri, a Celtic tribe from the Moselle River area in Germany. Her cult centered on the area around Trier, known to the Romans as Treveri Augustorum (French Trèves).
Looking at the Martian Manhunter now, what I find myself wondering (apart from why the green skin) is why Mars? Apart from alliteration, I mean.
No doubt its nearness played a part, although these days that works against him, as we know a great deal more about Mars now. The idea of human-like life on Mars has gone by the wayside. and if you asked anyone these days about Martians, they would probably think of Marvin the Martian instead.
Since the goddess Rosmerta often (not always) appears with the Roman god Mercury in both inscriptions and art, it is generally assumed that she is his consort, and the images that show her with his attributes indicate that he was the more powerful partner. There is a strong case to be made, however, for reading it the other way around.
