Late Republic and early Augustan, c. 27 BCE onward
by Titus Livius (Livy)

Early Principate, 98 CE
by Tacitus
Tacitus's biography of his father-in-law Gnaeus Julius Agricola, governor of Britain — at once a son-in-law's tribute, a study of how a good man serves under a bad emperor, and the source of the most quoted line of imperial criticism antiquity produced.
Classical Greece, early 4th century BCE
by Xenophon

High Empire, c. 110–120 CE
by Tacitus

Classical Athens, early 4th century BCE
by Plato
Plato's account of Socrates' defence speech at his trial in 399 BCE — the founding document of philosophy as a way of life, in which Socrates refuses to abandon the examined life even to save it, and the conflict of philosophy and the city is laid bare.
Classical Greece, 4th century BCE
by Xenophon
Xenophon's short account of Socrates' defence and the spirit in which he met his death — a portrait that explains his apparent arrogance at trial as the deliberate choice of a man who judged death preferable to the decline of old age.
Classical Greece, 4th century BCE
by Aristotle

Late Roman Republic, 58–51 BCE
by Gaius Julius Caesar
Caesar's seven-book first-person account of the Gallic campaign of 58–51 BCE, published while the war was still in progress — at once a military dispatch, a literary masterpiece of Latin prose, and a political instrument intended to shape Roman public opinion about a command the Senate could not control.
Classical Greece, late 4th century BCE
by Aristotle (or the Aristotelian school)

Classical Greece, 4th century BCE

by Plato

Late Roman Republic, 44 BCE
by Marcus Tullius Cicero
Cicero's three-book treatise on duty, written in the autumn of 44 BCE as he stood publicly against Antony — the most complete ancient statement of what a senator, magistrate or citizen owes to the Republic, and the single classical text that did the most work in the European moral tradition for the two millennia after.
Late Roman Republic, 54–51 BCE
by Marcus Tullius Cicero
Cicero's six-book dialogue on the mixed constitution and the dignity of public service, composed 54–51 BCE — partly lost, partly preserved in the closing *Somnium Scipionis*, partly recovered by Angelo Mai from a Vatican palimpsest in 1819.
Classical and early Hellenistic Greece, 4th–3rd century BCE
by Aristotle (and the Peripatetic school; authorship debated)

Classical Greece, 4th century BCE
by Aristotle
Aristotle's other major ethical treatise — parallel to the Nicomachean Ethics and sharing three books with it — an alternative and in places fuller treatment of virtue, flourishing and the good life, long neglected and now increasingly studied.
Early Principate, 98 CE
by Tacitus
Tacitus's ethnographic monograph on the peoples beyond the Rhine — antiquity's fullest account of the Germanic world, a mirror held up to Roman decline, and a text whose later misreading made it one of the most dangerous books the classical tradition produced.
Classical Athens, 4th century BCE
by Plato
Plato's confrontation between philosophy and rhetoric — and between two ways of life — in which Socrates argues, against the orator Gorgias and the ruthless Callicles, that it is better to suffer wrong than to do it, and that the good life is the just one.
late Warring States period, 3rd century BCE
by Han Fei
The synthesising masterwork of Chinese Legalism, gathering the doctrines of law, administrative method and positional power into the fullest ancient theory of the impersonal state — government that runs on system rather than on the virtue of rulers.
Classical Greece, 4th century BCE
by Xenophon
Xenophon's history of Greek affairs from 411 BCE, taking up Thucydides' unfinished narrative and carrying it through the fall of Athens, the Spartan hegemony and its collapse — a participant's history of the Greek world's long unravelling.
Classical Greece, 4th century BCE
by Xenophon
Xenophon's manual for the Athenian cavalry commander — a practical treatise on the duties of the hipparch that doubles as a compact study of leadership, drawn from his own experience of command and his lifelong horsemanship.
High Empire, c. 100–110 CE
by Tacitus
Tacitus's account of the year of the four emperors and the Flavian accession — the most vivid surviving anatomy of a Roman civil war, and the work that exposed what Tacitus called the secret of empire: that an emperor could be made somewhere other than Rome.

Roman Empire, c. 100 CE (subject reigned 336–323 BCE)
by Plutarch
Plutarch's biography of Alexander the Great, paired with Caesar — the Life whose famous preface states his whole method, that he writes lives and not histories, and that character shows more in a jest than in a battle.
Roman Empire, c. 100 CE (subject 100–44 BCE)
by Plutarch
Plutarch's biography of Julius Caesar, paired with Alexander — a study of supreme ability and unappeasable ambition, and a principal source through which later Europe read the fall of the Roman Republic.
Roman Empire, c. 100 CE (subject 95–46 BCE)
by Plutarch
Plutarch's biography of the Stoic senator who became the moral conscience of the dying Republic — a study of unbending integrity as both the noblest of virtues and, in the supple politics of the late Republic, a kind of liability.
Roman Empire, c. 100 CE (subject 106–43 BCE)
by Plutarch
Plutarch's biography of the Roman orator and statesman, paired with Demosthenes — a sympathetic but unsparing study of eloquence and vacillation in the Republic's last generation, and of the vanity that shadowed real greatness.
Roman Empire, c. 100 CE (subject traditionally 8th–7th century BCE)
by Plutarch
Plutarch's biography of the Spartan lawgiver, paired with Numa — the fullest ancient account of the Lycurgan constitution, and the text through which the early-modern republican tradition received the figure of the founder.
Roman Empire, c. 100 CE (subject c. 495–429 BCE)
by Plutarch

Classical Greece, late 5th / early 4th century BCE
by Ctesias of Cnidus
The lost Persian history of Ctesias of Cnidus — a Greek physician at the Achaemenid court whose twenty-three-book account survives only in fragments and epitomes, and the platform's clearest case study in how a Greek source on Persia can be both insider-informed and deeply unreliable.

Classical Greece, 4th century BCE
by Xenophon
Xenophon's account of a dinner party at which Socrates and his companions discuss what each is most proud of — a lighter, more genial Socratic work that reads beside Plato's Symposium as a second window on Socrates among his friends.

by Gaius Sallustius Crispus

Classical Greece, 5th century BCE
by Herodotus of Halicarnassus

by Gaius Sallustius Crispus

Late Antiquity / early Byzantine, c. 600 CE
by Attributed to the Emperor Maurice
