Belenos or Bolgios?

From the wiki:-

Cassivellaunus was a historical British chieftain who led the defence against Julius Caesar's second expedition to Britain in 54 BC. The first British person whose name is recorded, Cassivellaunus led an alliance of tribes against Roman forces, but eventually surrendered after his location was revealed to Caesar by defeated Britons.

Cassivellaunus made an impact on the British consciousness. He appears in British legend as Cassibelanus , one of Geoffrey of Monmouth 's kings of Britain, and in the Mabinogion , the Brut y Brenhinedd and the Welsh Triads as Caswallawn , son of Beli Mawr . His name in Brythonic *Kaiwellaunos , from *kai- "passion, love, hate" + *weln- "to lead" + -aunos "one who", translates as either "leader of the Cassi [tribe]", and therefore may be more of a title rather than his actual given name (although the two need not be mutually exclusive), or as "The Passionate Leader".
