"Diogenes made a virtue of poverty. He begged for a living and slept in a large stone jar in the marketplace. He became notorious for his philosophical stunts such as carrying a lamp in the daytime, claiming to be looking for an honest man. He embarrassed Plato, disputed his interpretation of Socrates and sabotaged his lectures. Diogenes was also responsible for publicly mocking Alexander the Great."

Jean-Léon Gérôme, Diogenes, 1860
