Laughter was always a favourite device of ancient monarchs and tyrants, as well as being a weapon used against them. The good king, of course, knew how to take a joke. The tolerance of the Emperor Augustus in the face of quips and banter of all sorts was still being celebrated four centuries after his death. One of the most famous one-liners of the ancient world, with an afterlife that stretches into the twentieth century (it gets retold, with a different cast of characters but the same punchline, both in Freud and in Iris Murdoch’s The Sea, The Sea), was a joking insinuation about Augustus’ paternity. Spotting, so the story goes, a man from the provinces who looked much like himself, the Emperor asked if the man’s mother had ever worked in the palace. “No”, came the reply, “but my father did.” Augustus wisely did no more than grin and bear it. Tyrants, by contrast, did not take kindly to jokes at their own expense, even if they enjoyed laughing at their subjects. Sulla, the murderous dictator of the first century BC, was a well-known philogelos (“laughter-lover”), while schoolboy practical jokes were among the techniques of humiliation employed by the despot Elagabalus. He is said to have had fun, for example, seating his dinner guests on inflatable cushions, and then seeing them disappear under the table as the air was gradually let out.
