The Library

Forty Centuries of Christian Writing

1780 works catalogued century by century, from the literature the Bible was written among to the present — each with a note on what it is, why it lasted, and where to read it.

301–400

The Fourth Century

144 works

c. 303–304

Latin

On the Workmanship of God

De Opificio Dei

Lactantius · c. 250 – c. 325

Written while the persecution was running, and about anatomy. Lactantius walks through the body part by part — the eye, the ear, the hand, the arrangement of the teeth — arguing that nothing in it is accidental, against Epicurus, who said the organs came first and their uses after.

c. 300–305

Greek

On the Mysteries of the Egyptians

De Mysteriis

Iamblichus of Chalcis · c. 245 – c. 325

An answer to Porphyry, who had asked why gods should need rites at all. Iamblichus replies that the soul cannot think its way up: it is joined to the divine by acts whose power lies in the acts themselves, not in the understanding of whoever performs them — names, stones, incense, and prayer.

306

Greek

The Canonical Letter

Peter of Alexandria · d. 311

Fourteen rulings grading the penance owed by Christians who failed under persecution — those who bribed officials, those who sent slaves in their place, those who fled — with a different penalty for each.

Alexandrian · CanonsRead elsewhere

c. 308–310; partly survives

Greek

Apology for Origen

Pamphilus of Caesarea · d. 309

Written in prison with Eusebius's help, answering charge by charge the accusations against Origen's orthodoxy, mostly by quoting him at length.

Early Church · ApologyRead elsewhere

c. 303–311

Latin

The Divine Institutes

Divinae Institutiones

Lactantius · c. 250–c. 325

Seven books written during the Great Persecution, setting out Christianity as a complete philosophy — false religion, the origin of error, justice, true worship, and the life of blessedness — in the most polished Latin any Christian had yet written.

Early Church · ApologyFull text

c. 311–313

Greek

Against Hierocles

Eusebius of Caesarea · c. 260 – c. 340

A governor active in the persecution had written a book setting Apollonius of Tyana beside Christ and arguing that the pagan wonder-worker was the better attested of the two. Eusebius answers by going through Philostratus's biography and asking what in it a reasonable person would actually believe.

Early Church · PolemicMatthewJohnActsRead elsewhere

c. 311–313

Greek

The Martyrs of Palestine

Eusebius of Caesarea · c. 260 – c. 340

An eyewitness record of the Diocletianic persecution in the province where Eusebius lived, year by year and name by name — the mines at Phaeno, the men blinded in one eye and hamstrung in one foot and sent to labour, and his own teacher Pamphilus in prison for two years before the end.

c. 311; revised later, survives in Armenian and in Jerome's Latin

Greek, surviving in Armenian and Latin

The Chronicle

Chronicon

Eusebius of Caesarea · c. 260 – c. 340

A summary of world history followed by parallel columns — Hebrews, Assyrians, Egyptians, Greeks, Romans — ruled across the page so that any year can be read simultaneously in every kingdom that existed in it, from Abraham to the writer's own day.

Early Church · ChronicleGenesisDanielLukeRead elsewhere

c. 313–316

Latin

On the Deaths of the Persecutors

De Mortibus Persecutorum

Lactantius · c. 250–c. 325

A grimly satisfied account of how each emperor who persecuted the church came to a bad end, closing with Constantine's victory and the edict of toleration.

Early Church · HistoryFull text

c. 313–320

Greek

Preparation for the Gospel

Praeparatio Evangelica

Eusebius of Caesarea · c. 260–339

Fifteen books arguing that Christians were right to prefer Hebrew scripture to Greek philosophy, assembled from enormous quotations of pagan authors.

Early Church · ApologyFull text

c. 313–316

Latin

On the Anger of God

De Ira Dei

Lactantius · c. 250 – c. 325

Against the Stoics and Epicureans, who agreed that God cannot be angry. Lactantius argues that a God who cannot be angry cannot love either, since the two are one faculty turned two ways — and quotes Epicurus's dilemma in full: is God willing to prevent evil but not able, or able but not willing.

Western · TreatisePsalmsRomansDeuteronomyNahumFull text

c. 318

Greek

On the Incarnation

De Incarnatione Verbi Dei

Athanasius of Alexandria · c. 296–373

A short, unhurried argument that the Word took a body because a creation running back toward nothing could only be restored from inside it — and that the resurrection is the demonstrable proof, visible in martyrs who no longer fear dying.

Early Church · TheologyJohnHebrewsGenesisFull text

c. 318

Greek

Against the Heathen

Contra Gentes

Athanasius of Alexandria · c. 296–373

The first half of a two-part work, arguing that idolatry is a fall from the knowledge of God available through the soul and the order of creation.

Alexandrian · ApologyFull text

c. 320; survives in fragments

Greek

Thalia

Arius · c. 256–336

A popular verse exposition, apparently written to be sung, arguing that the Son is the first and greatest of creatures, made before time but not eternal.

Arian · PoetryRead elsewhere

c. 314–324; ten of twenty books survive

Greek

Demonstration of the Gospel

Demonstratio Evangelica

Eusebius of Caesarea · c. 260 – c. 340

The companion to the Preparation, and the harder half: having shown why Christians abandoned Greek religion, Eusebius now has to show why they kept the Jewish scriptures while refusing the Jewish law. The answer runs through the prophets text by text, arguing that the patriarchs lived by a religion older than the law and that Christians have returned to it.

Early Church · ApologeticIsaiahPsalmsGenesisMicahRead elsewhere

c. 320–330

Greek

On the Place Names in Holy Scripture

Onomasticon

Eusebius of Caesarea · c. 260–339

The Creed of Nicaea

The Council of Nicaea

The confession drawn up by the first ecumenical council, declaring the Son to be of one substance with the Father, and anathematising those who said there was a time when he was not.

Greek

The Church History

Historia Ecclesiastica

Eusebius of Caesarea · c. 260–339

Early Church · HistoryActsRead elsewhere

c. 329–330

Latin

Four Books of the Gospels

Evangeliorum Libri Quattuor

Juvencus

The gospel story, mostly Matthew, recast in some thirty-two hundred lines of Virgilian hexameter by a Spanish priest of noble birth. The preface says plainly what it is for: Homer and Virgil will burn with the world, but a poem carrying the deeds of Christ will not.

Western · PoetryMatthewLukeJohnRead elsewhere

333

Latin

The Bordeaux Pilgrim

Itinerarium Burdigalense

Anonymous

A bare itinerary from Bordeaux to Jerusalem listing every staging post and change of horses, with terse notes on the holy places seen at the end.

c. 334–337

Latin

The Mathesis

Julius Firmicus Maternus

The longest astrological handbook to survive from antiquity: eight books on the houses, the aspects, and what each configuration produces in a life, written with real piety toward a cosmos in which the stars carry out the will of a supreme mind.

c. 337–339

Greek

The Life of Constantine

Vita Constantini

Eusebius of Caesarea · c. 260–339

Orationes contra Arianos

Athanasius of Alexandria · c. 296–373

Three long discourses arguing text by text that the Son is eternally begotten, and that if he were a creature then creatures would be worshipping a creature.

c. 335–340; survives in fragments

Greek

Against Asterius

Marcellus of Ancyra · c. 285 – c. 374

A defender of Nicaea who defended it too far: the Word was in God from eternity but became Son only at the incarnation, and at the end will be reabsorbed, so that the kingdom of Christ has a term. Eusebius wrote two books against him.

Contested · Polemic1 CorinthiansLukeJohnColossiansRead elsewhere

c. 346–350

Latin

On the Error of Profane Religions

Greek

On the Decrees of the Council of Nicaea

De Decretis

Athanasius of Alexandria · c. 296–373

Alexandrian · ApologyFull text

c. 340–380 and later

Syriac

The Acts of the Persian Martyrs

Anonymous

Accounts of the great persecution under Shapur II, in which Christians were taxed at double rate as suspected partisans of Rome and their clergy killed when they refused to collect it. Simeon bar Sabbae is executed with a hundred of his clergy on the eve of Good Friday.

History of the Arians

359

Latin

On the Synods

De Synodis

Hilary of Poitiers · c. 310 – c. 367

Written in exile to the bishops of Gaul, setting out every Eastern creed of the previous thirty years in turn and asking, of each, whether it can be read in an orthodox sense. He is unusually willing to grant that men who reject his vocabulary may hold his faith.

The Life of Antony

Early Church · BiographyMatthewFull text

c. 360

Greek

The Apology

Eunomius of Cyzicus · c. 325 – c. 395

A tight, almost geometric argument that God's essence is unbegottenness; that the Son, being begotten, is therefore of a different essence; and — most provocative of all — that the human mind can know God's essence as well as God knows it, since a name given rightly reaches the thing itself.

Arian · TreatiseJohnColossiansProverbsActsRead elsewhere

c. 359–361

Greek

Letters to Serapion on the Holy Spirit

Athanasius of Alexandria · c. 296 – 373

Written from hiding in the desert to a bishop who had reported a group willing to confess the Son fully but not the Spirit. Athanasius argues that a created Spirit would break the Trinity into unlike parts, and that since we are made divine by the Spirit, the Spirit cannot be a creature.

Alexandrian · LettersJohn1 Corinthians2 CorinthiansRomansRead elsewhere

c. 356–360

Latin

On the Trinity

De Trinitate

Hilary of Poitiers · c. 310–367

Twelve books written in exile in Asia Minor, bringing the Greek arguments against Arianism into Latin for a Western church that had barely followed the controversy.

Latin

Against Arius

Adversus Arium

Marius Victorinus · c. 290 – c. 364

A famous Roman rhetorician who converted late and publicly, writing Trinitarian theology in the language of Neoplatonic metaphysics: being, life, and understanding as one movement out and back, with the Son as the act by which what is at rest becomes what moves.
