Dame Judi Dench as Lady Macbeth in the sleepwalking scene

Today in 1606 is the first recorded performance of Macbeth.

Macbeth is the most concentrated study of tyranny as a force within an individual soul, which has to be cast out of that as well as out of society.  The tyrant exists because the victims are tyrants to themselves.  (CW 15, 243)
