Have you ever played the telephone game? One person starts with a sentence that they say to second person, who then says it to a third person, and so on through the group trying to keep the sentence the same. What we find is that the sentence you start with is often very unlike the sentence you end with.
Imagine you played the telephone game. The sentence you started with was:
WE BOUGHT EGGS AT THE MARKET
And by the time you got to the 10th person telling it the sentence became
THE CLOWN IN THE WHITE MAKEUP AND RED NOSE ROSE FROM THE DEAD
Wow, that’s quite the change. Make a story line showing the steps in which the first sentence slowly changed into the last sentence.
Why might this be a problem in doing ancient history before they had cameras and most people couldn’t read or write?
