Well,ok,I'll try to explain it. It's a sentence from Shakespeare's Hamlet, when he understands that the father was killed by his brother and then took the mather of Hamlet as spouse. With this sentence he expresses the "out of position or "dislocation" of the flow of the time. The museum uses this sentence to made an exhibition about the stratification of time instead of a regular flow that goes in one direction.
Em, I don't know if I explained myself correctly...
