10. Why We Still Read Plutarch's Lives Today

No one in recorded history conquered more land in less time. But that is not why Plutarch wrote about Alexander. He is not interested in the map. He wants to look inside the man who drew it — at the place where genius and destruction lived side by side, and eventually could no longer be told apart.

A Fire From the Beginning

Alexander was born in 356 BC in Macedonia. His father was Philip II — the king who forged Macedonia into the most formidable military power in Greece. His mother was Olympias — fierce, mystical, a princess of Epirus who believed her son had been fathered by a god. Neither parent was who Alexander wanted to be. He wanted to be more.

The ambition showed early. When news arrived of one of Philip's victories, the boy would grow quiet and withdrawn. His companions asked why. He told them without hesitation.

"My father will leave me nothing to conquer."

— Alexander, Plutarch's Lives, Alexander

The Student of Aristotle

Philip hired the greatest philosopher alive to tutor his son. From age thirteen to sixteen, Alexander studied under Aristotle — philosophy, medicine, natural science, literature. He developed a particular love for Homer's Iliad, which he kept under his pillow on campaign alongside a dagger, annotated in Aristotle's hand.

BucephalusAt twelve years old, Alexander tamed a horse that no one else could handle. He noticed the animal was terrified of its own shadow, turned its head toward the sun, and the horse went calm. Philip watched, and wept. "My son," he said, "Macedonia is too small a kingdom for you." The horse was named Bucephalus. Alexander rode him until the day the horse died, deep in India — and named a city after him.

The Conquest Begins

Philip was assassinated in 336 BC. Alexander became king at twenty. Two years later, he launched his campaign against Persia — the greatest empire the world had known. No one seriously believed he could win.

• 334 BC Battle of the GranicusFirst engagement against Persian forces. Alexander crosses into Asia and defeats the Persian garrison.
• 333 BC The Gordian KnotAn ancient prophecy: whoever untied the knot would rule Asia. Alexander drew his sword and cut through it.
• 331 BC Battle of GaugamelaDarius III defeated decisively. Persepolis falls. Alexander becomes lord of the Persian Empire.
• 326 BC The Edge of IndiaAt the Hyphasis River, his army refuses to march further. For the first time, Alexander is stopped — not by an enemy, but by his own men.

Plutarch is less interested in the battles than in the moments between them. At Gordium, when Alexander cut the knot rather than untied it, he was not simply solving a puzzle. He was announcing something about who he was: a man who rewrites the rules of the problem rather than playing by them.

The King Who Changed

The deeper Alexander went into Persia, the more he became someone else. He began wearing Persian robes. He demanded that his court prostrate themselves before him in the Persian fashion. He proclaimed himself a son of the gods. His Macedonian generals seethed. The king they had marched beside was disappearing.

The Killing of CleitusIn 328 BC, at a banquet, Alexander's old friend and general Cleitus openly mocked his adoption of Persian customs and questioned whether his achievements surpassed his father's. In a drunken fury, Alexander seized a spear and ran him through. Cleitus died instantly. When Alexander sobered the next morning, he wept for days and refused to eat. The grief was real. Cleitus was still dead.

Plutarch holds this scene at the center of his account. Alexander's courage in battle was never in doubt. But power had changed him. When no one can say no to you, something essential begins to rot. Alexander is Plutarch's most dramatic answer to the question of what unchecked authority does to even the most gifted of men.

Hephaestion

There is one name that runs through Alexander's life like a second thread. Hephaestion — his closest friend since childhood, his companion on every campaign. When the two of them visited Troy early in the expedition, Alexander laid a wreath on the tomb of Achilles. Hephaestion laid one on the tomb of Patroclus. No explanation was needed.

In 324 BC, Hephaestion died suddenly of fever. Alexander's grief was beyond consolation. He stopped eating. He lay beside the body for days. Those around him said he no longer seemed to be alive himself. Within a year, Alexander was dead too.

Babylon, 323 BC

Alexander fell ill in Babylon in June of 323 BC. He held on for ten days. Then he was gone. He was thirty-three years old. The empire he had spent his entire adult life building fractured within months of his death. His generals divided it among themselves. It was never reunited.

Plutarch's final question about Alexander is one he refuses to answer neatly: was this man great, or merely terrifying? He built libraries and cities. He spread Greek culture across three continents. He also killed his friend in a rage, crushed those who questioned him, and declared himself divine. Both things are true. Plutarch does not resolve them. He simply holds them together and asks you to sit with the discomfort.
