Arc,
You are right. Moreover, unfortunately, very often the truth is not uncovered even centures after.
Today I was using a Moscow metro (subway, underground, U-bahn, ...). There is a train there totally dedicated to Shakespeare. Nicely decorated with lots of quotes in original and Russian translation. In front of my eyes there was the following text from "King Lear":
"Time shall unfold what plighted cunning hides,
Who covers faults at last with shame derides.
Well may you prosper"
I am afraid the author (or Cordelia) was wrong in the first line when using the word "unfold" :-(
