11. Behold! human beings living in a under-
ground den, which has a mouth open to-
wards the light and reaching all along
the den; here they have been from their
childhood, and have their legs and necks
chained so that they cannot move, and can
only see before them, being prevented by
the chains from turning round their heads.
Above and behind them a fire is blazing at
a distance, and between the fire and the
prisoners there is a raised way; and you
will see, if you look, a low wall built along
the way, like the screen which marionette
players have in front of them, over which
they show the puppets.
I see.
And do you see, I said, men passing along
the wall carrying all sorts of vessels, and
statues and figures of animals made of
wood and stone and various materials,
which appear over the wall? Some of them
are talking, others silent.
You have shown me a strange image, and
they are strange prisoners
(Plato 1994: Book VII).
