Lactantius in the context of "The Divine Institutes"

The Edict of Milan (Latin: Edictum Mediolanense; Greek: Διάταγμα τῶν Μεδιολάνων, Diatagma tōn Mediolanōn) was the February 313 agreement to treat Christians benevolently within the Roman Empire. Western Roman Emperor Constantine I and Emperor Licinius, who controlled the Balkans, met in Mediolanum (modern-day Milan) and, among other things, agreed to change policies towards Christians following the edict of toleration issued by Emperor Galerius two years earlier in Serdica. The Edict of Milan gave Christianity legal status and a reprieve from persecution but did not make it the state church of the Roman Empire, which occurred in AD 380 with the Edict of Thessalonica, when Nicene Christianity received normative status.

The document is found in Lactantius's De mortibus persecutorum and in Eusebius of Caesarea's History of the Church with marked divergences between the two. Whether or not there was a formal 'Edict of Milan'  is no longer really debated among scholars, who generally reject the story as it has come down in church history.

Various early Christian writers wrote gospels and other books, some of which were canonized as the New Testament canon developed. The Apostolic Fathers were prominent writers who are traditionally understood to have met and learned from Jesus's personal disciples. The Church Fathers are later writers with no direct connection to the disciples (other than the claim to apostolic succession). Early Christian apologists tried to defend Christianity against its critics, especially the Ancient Greek and Roman philosophers. Dates given, if not otherwise specified, are of their writings or bishopric, not of their lives.

De mortibus persecutorum (On the Deaths of the Persecutors) is a hybrid historical and Christian apologetical work by the Roman philosopher Lactantius, written in Latin sometime after AD 316.

The Battle of the Milvian Bridge took place between the Roman Emperors Constantine I and Maxentius on 28 October AD 312. It takes its name from the Milvian Bridge, an important route over the Tiber. Constantine won the battle and started on the path that led him to end the Tetrarchy and become the sole ruler of the Roman Empire. Maxentius drowned in the Tiber during the battle; his body was later taken from the river and decapitated, and his head was paraded through the streets of Rome on the day following the battle before being sent to Africa.

According to Christian chroniclers Eusebius of Caesarea and Lactantius, the battle marked the beginning of Constantine's conversion to Christianity. Eusebius of Caesarea recounts that Constantine and his soldiers had a vision sent by the Christian God. This was interpreted as a promise of victory if the sign of the Chi Rho, the first two letters of Christ's name in Greek, was painted on the soldiers' shields. The Arch of Constantine, erected in celebration of the victory, certainly attributes Constantine's success to divine intervention; however, the monument does not display any overtly Christian symbolism.

Hortensius (Latin: [hɔrˈtẽːsi.ʊs]) or On Philosophy is a lost dialogue written by Marcus Tullius Cicero in the year 45 BC. The dialogue—which is named after Cicero's friendly rival and associate, the speaker and politician Quintus Hortensius Hortalus—took the form of a protreptic. In the work, Cicero, Hortensius, Quintus Lutatius Catulus, and Lucius Licinius Lucullus discuss the best use of one's leisure time. At the conclusion of the work, Cicero argues that the pursuit of philosophy is the most important endeavor.

While the dialogue was extremely popular in Classical Antiquity, the dialogue only survived into the sixth century AD before it was lost. Today, it is extant in the fragments preserved by the prose writer Martianus Capella, the grammarians Maurus Servius Honoratus and Nonius Marcellus, the early Christian author Lactantius, and the Church Father Augustine of Hippo (the latter of whom explicitly credits the Hortensius with encouraging him to study the tenets of philosophy).

The phoenix (sometimes spelled phenix in American English; see spelling differences) is a legendary immortal bird that cyclically regenerates or is otherwise born again. Originating in Greek mythology, it has analogs in many cultures, such as Egyptian and Persian mythology. Associated with the sun, a phoenix obtains new life by rising from the ashes of its predecessor. Some legends say it dies in a show of flames and combustion, while others say that it simply burns to death and decomposes before being born again. In the Motif-Index of Folk-Literature, a tool used by folklorists, the phoenix is classified as motif B32.

The origin of the phoenix has been attributed to Ancient Egypt by Herodotus and later 19th-century scholars, but other scholars think the Egyptian texts may have been influenced by classical folklore. Over time, the phoenix motif spread and gained a variety of new associations; Herodotus, Lucan, Pliny the Elder, Pope Clement I, Lactantius, Ovid, and Isidore of Seville are among those who have contributed to the retelling and transmission of the phoenix motif. Over time, extending beyond its origins, the phoenix could variously "symbolize renewal in general as well as the sun, time, the Roman Empire, metempsychosis, consecration, resurrection, life in the heavenly Paradise, Christ, Mary, virginity, the exceptional man, and certain aspects of Christian life". Some scholars have claimed that the poem De ave phoenice may present the mythological phoenix motif as a symbol of Christ's resurrection.

Flavius Julius Crispus (/ˈkrɪspəs/; c. 300 – 326) was the eldest son of the Roman emperor Constantine I, as well as his junior colleague (caesar) from March 317 until his execution by his father in 326. The grandson of the augustus Constantius I, Crispus was the elder half-brother of the future augustus Constantine II and became co-caesar with him and with his cousin Licinius II at Serdica, part of the settlement ending the Cibalensean War between Constantine and his father's rival Licinius I. Crispus ruled from Augusta Treverorum (Trier) in Roman Gaul between 318 and 323 and defeated the navy of Licinius I at the Battle of the Hellespont in 324, which with the land Battle of Chrysopolis won by Constantine forced the resignation of Licinius and his son, leaving Constantine the sole augustus and the Constantinian dynasty in control of the entire empire. It is unclear what the legal status of the relationship Crispus's mother Minervina had with Constantine was; Crispus may have been an illegitimate son.

Crispus's tutor in rhetoric was the Late Latin historian of Early Christianity Lactantius. After his elevation to imperial rank, at which point he was also entitled princeps iuventutis ("Prince of Youth"), the Latin rhetorician Nazarius composed a panegyric preserved in the Panegyrici Latini, which honoured Crispus's military victories over the Franks in c. 319. Crispus was three times Roman consul, for the years 318, 321, and 324.

De ave phoenice is a poem attributed to the early Christian apologist writer Lactantius. The poem is not overtly Christian; scholars point to certain aspects of the text to support their view that the author intended a Christian interpretation of the phoenix. They interpret the mythological phoenix motif as symbolic of Christ and resurrection.
