Anecdotes

Demetrius of Phalerum governed Athens for ten years on behalf of Macedonia. The flattering Athenians erected an extraordinary number of statues in his honor — ancient tradition speaks of 360, one for each day of the year. But when he fell from grace in 307 BC, the crowd toppled almost all of them in a single night.

According to an anecdote reported by Diogenes Laertius, some of his fallen statues were supposedly melted down to be turned into chamber pots, so brutal and humiliating was the reversal of public opinion against him.

Having taken refuge in Alexandria, Demetrius advised King Ptolemy I and played a key role in creating the great Library and the Museum. It is said that he dreamed of gathering all the books in the world in a single place, laying the foundations of what would become the greatest center of learning in antiquity.

A disciple of Aristotle at the Lyceum, Demetrius was one of the few philosophers to actually wield political power. In Athens he established magistrates tasked with overseeing women and curbing extravagance at funerals and banquets, blending moral philosophy with sumptuary laws.

His downfall was as cruel as his death: according to Diogenes Laertius, having become a sidelined adviser at Ptolemy's court, he is said to have died from the bite of an asp, perhaps in disgrace, far from the Athens he had once governed.
