A brief orientation
Plutarch was born in Chaeronea, in Boeotia, around the middle of the first century CE. He studied at the Platonic Academy in Athens, travelled in Egypt and in Italy, gained Roman citizenship and the Roman name Lucius Mestrius Plutarchus, and spent most of his life back in Chaeronea, where he served for many years as one of the two priests at the oracle of Apollo at Delphi.
His writing falls into two great groups: the Parallel Lives, a sequence of paired biographies of Greek and Roman statesmen, soldiers and lawgivers; and the Moralia, a substantial collection of essays and dialogues on ethics, religion, politics, education, friendship and much else.
What the Lives are doing
The Lives are not chronicles. Plutarch says explicitly that he is writing biographies, not histories — that what interests him is the character a person's life reveals, often more clearly in a small incident than in a great battle. The pairings (Alexander with Caesar, Theseus with Romulus, Demosthenes with Cicero, and so on) are designed for comparison: many of the pairs end with a brief comparative essay (synkrisis) drawing the two figures against each other.
Why he matters for Virtue & Power
Plutarch is the classical author who, more than any other, treats the shape of a life as the right unit for moral and political reflection. The European tradition has read him in exactly that spirit: Montaigne, Shakespeare (through Sir Thomas North's 1579 English translation), Rousseau and Emerson are all serious readers of Plutarch, and the modern revival of virtue ethics has returned to him often as a source for the case-by-case texture that abstract ethical theory tends to lose.
