Camulus

[1] Camulus was an important god of Roman Britain and Gaul, especially among the Belgae and the Remi,[1] Gaulish tribes that originate from the areas of modern day Belgium, Luxembourg, Northern France and parts of Germany and the Netherlands.

[1] Camulus is named in combination with Mars in inscriptions coming from Reims,[3] Arlon,[4] Kruishoutem,[5] Rindern,[6] Mainz,[7] Bar Hill Fort near the Antonine Wall,[8] Sarmizegetusa,[9] and Southwark, London.

[10][11] The town Camulodunum (now Colchester) in Essex may have been named after him (and is the conjectured basis for the legendary city of Camelot).

[12] Camulodunum is a Latinised form of the Brittonic Camulodūnon from Camulos plus dūnon "(hill)fort, stronghold", a reference to the town's extensive Iron Age earthwork defences.

[13] Attempts from the 20th century and earlier to link the name Camulus with the nursery rhyme character Old King Cole, and with Irish mythological Cumhall, the hero Fionn's father, have been rejected by contemporary scholars.
