Höhlengleichnis
The employment and occupation of the fool played a significant role in the ancient world. The Ancient Greek authors Xenophon and Athenaeus wrote of normal men hired to behave as insane fools and clowns while the Roman authors Lucian and Plautus left records of powerful Romans who housed deformed buffoons famous for their insolence and brazen madness. Plato, through the guise of Socrates, provides an early example of the wisdom of the fool in "The Republic" through the figure of an escaped prisoner in The Allegory of the Cave. The escaped prisoner, part of a group imprisoned from birth, returns to free his fellow inmates but is regarded as a madman in his attempts to convince his shackled friends of a greater world beyond the cave.
