Many Catters have heard the name somewhere else-- in Gilbert and Sullivan's "model of a modern Major-general" Gen'l Staley claims to be able to give you "every detail of Caractacus's uniform" . . . first place I ever heard the name and didn't think of it again till many years later when I saw Ian Fleming's "chitty chitty bang bang" where the inventor was (drum roll please) Caractacus Potts. . . later on in I. Claudius I found why the name might be a good one for Britons
