History isn't like that. History unravels gently, like an old sweater. It has been patched and darned many times, reknitted to suit different people, shoved in a box under the sink of censorship to be cut up for the dusters of propaganda, yet it always - eventually - manages to spring back into its old familar shape. History has a habit of changing the people who think they are changing it. History always has a few tricks up its frayed sleeve. It's been around a long time.
Terry PratchettThe Four Horsemen whose Ride presages the end of the world are known to be Death, War, Famine, and Pestilence. But even less significant events have their own Horsemen. For example, the Four Horsemen of the Common Cold are Sniffles, Chesty, Nostril, and Lack of Tissues; the Four Horsemen whose appearance foreshadows any public holiday are Storm, Gales, Sleet, and Contra-flow.
