One evening at a palace dinner party, in about 40AD, a couple of nervous aristocrats asked the emperor Caligula why he was laughing so heartily. “Just at the thought that I’d only have to click my fingers and I could have both your heads off!” It was, actually, a favourite gag of the emperor (he had been known to come out with it when fondling the lovely white neck of his mistress). But it didn’t go down well.
Laughter and joking were just as high-stakes for ancient Roman emperors as they are for modern royalty and politicians. It has always been bad for your public image to laugh in the wrong way or to crack jokes about the wrong targets. The Duke of Edinburgh got into trouble with his (to say the least) ill-judged “slitty-eyed” quip, just as Tony Abbott recently lost votes after being caught smirking about the grandmother who said she made ends meet by working on a telephone sex line. For the Romans, blindness – not to mention threats of murder – was a definite no-go area for joking, though they treated baldness as fair game for a laugh (Julius Caesar was often ribbed by his rivals for trying to conceal his bald patch by brushing his hair forward, or wearing a strategically placed laurel wreath). Politicians must always manage their chuckles, chortles, grins and banter with care.
