In the Middle Ages, a knight’s fortune (like that of everyone else) was subject to change, just like today. But during that time, the
Wheel of Fortune was not a game show. It was a concept people actually believed - a kind of fate that was subject to the unpredictable "ups and downs" of life.
In a book that remained popular for 12 centuries, Boethius wrote of Fortune:
I turn the whirling wheel and my circle spins. I am glad to change the lowest to the highest, and the highest to the lowest. Mount up if you will, provided you do so under this condition, that you will not maintain that I do you wrong though you descend down when the rules of my game require it.
If a knight’s fortune could be up one day and down the next, how would a peasant, who dared to lead a
rebellion against his king (Richard II), survive life’s vagaries?
For Wat Tyler, the answer to that question was swift and lethal.
