He is a deity of warfare who was very popular with the ancient Brits and Gauls. The Romans identified him with MARS and subsequently tangled the two together as best they could.
CAMULUS was popular enough to have given his name to several places, notably Camulodunum, ye olde Roman name for Colchester in Essex, England.
Trying to pretend this was the original location of Camelot seems to be taking a bit of a liberty. We happen to know his first residence was in Belgium, which may explain something.
There is wild speculation that CAMULUS could also be the Old King Cole of nursery rhyme fame. In which case Nat ‘King’ Cole with his trio and penchant for heavy smoking could — if you wish to continue in this vein — have been a descendant.
None of this seems particularly suited to a God of War. We apologize for the lack of exciting battles and horrible bloodstained warriors in this entry.
