Pirner was fascinated by the figure of Diogenes of Sinope (c.400 - 323 or 325 BC), one of the most radical and best-known exponents of Cynism. Cynism, a trend in Greek philosophy, attracted people disillusioned with the social order and moral values of their time. Supposedly a counterfeiter, Diogenes left his native Sinope and went into exile. In Athenes he became acquainted with Cynic philosophy and practised it in his way of life. In line with this philosophy he led no settled life, lived in a tub and scorned the world around him.
