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.

The Athenians set up three hundred and sixty statues of him, most of them on horseback or mounted on chariots; and it took no more than three hundred days to erect them, such was the haste.

Daily Life
Morning
During his time in government, Demetrius began the day early by receiving citizens and officials, reading decrees and reports unrolled on scrolls. As a philosopher trained at the Lyceum, he also devoted a moment to reflection and to reading the texts of Aristotle.
Afternoon
The afternoon was spent at the Agora or in the public buildings, dispensing justice, overseeing the enforcement of the laws, and conversing with other learned men. In Alexandria, these hours were taken up with advising the king and organizing the collection of books for the Library.
Evening
In the evening, he often took part in banquets (symposia) where wine diluted with water mingled with music and philosophical conversation. Demetrius, renowned for his taste for luxury despite his austere laws, enjoyed these moments of exchange among cultivated men.
Food
His diet rested on the Mediterranean triad: barley or wheat bread, olive oil, and wine. To these were added fish, vegetables, cheeses, figs, and honey, with meat remaining reserved for festivals and sacrifices.
Clothing
He wore the tunic (chiton) of linen or wool, covered by the large draped cloak (himation) that marked out the citizen and the philosopher. Leather sandals completed the outfit, and it is said that he took care of his appearance, perfuming himself and dyeing his hair.
Housing
Demetrius lived in the house of a well-to-do citizen, arranged around an inner courtyard, with reception rooms for banquets. In Alexandria, he lived among the entourage of the Ptolemaic royal court, close to the palace and the Museum.
