Life of Constantine the great (Greek: Βίος Μεγάλου Κωνσταντίνου; Latin: Vita Constantini) is a panegyric written in Greek in honor of Constantine the Great by Eusebius of Caesarea in the 4th century AD. It was never completed due to the death of Eusebius in 339. The work provides scholars with one of the most comprehensive sources for the religious policies of Constantine's reign.[1] In addition to detailing the religious policies of the Roman Empire under Constantine, Eusebius uses Life of Constantine to engage several of his own religious concerns, such as apologetics, as well as a semi-bibliographic account of Constantine. Its reliability as a historical text has been called into question by several historians, most notably Timothy Barnes, because of its questionable motives and writing style.


Divided into four books,[2] Life of Constantine begins with the declaration that Constantine is immortal. This opening sets the tone for the rest of the work, a general glorification and deification of the Emperor and his works on Earth. The work progresses into Constantine’s time under the Emperor Diocletian. Constantine is contrasted with the tyrannical Diocletian, whose persecution of Christians and oppressive rule accentuates the presentation of Constantine as a strong Christian and a just man. This section also established the overarching metaphor in the work, as Eusebius likens Constantine to Moses. Eusebius suggests that it was God’s will to raise Constantine to emperor, as a reliever of the Christian torment in the Empire.

Eusebius moves on from the introduction to Constantine’s military exploits for the remainder of Book 1 and half of Book 2. The first of which, the campaign against Maxentius, contains perhaps the most famous scene in the Life of Constantine, the vision of Constantine. This section has generated ample controversy, as there is much suspicion regarding the validity of the story. Eusebius claimed that he heard the story from the mouth of Constantine himself, however much of modern scholarship agrees that the stories is a distortion of facts or completely fabricated.[3] The same account is often compared to Lactantius’, which provides a radically different depiction of the same story.[3] Eusebius moved on to describe Constantine’s next military campaign, the war against Licinius. Eusebius facilitates in the blackening of Licinius, who was pro-Christian, that was started by Constantine as imperial propaganda to justify the aggression against Licinius.[4]

The work transitions from military campaigns to the religious rule of Constantine. The rest of book 2 ends with the outlining of the religious problems faced by Constantine. Book 3 is largely concerned with Constantine’s constructive settlement of the various religious problems. The section includes the only continuous contemporary account of the Council of Nicaea[5] as well as the pilgrimage to Bordeaux.[6] The Council of Nicaea has been examined closely by scholars for bias however, as Eusebius was himself very involved in the politics of the council.[5] The remainder of the book deals with the ecclesiastical laws of Constantine. Eusebius focuses much of his attention in painting Constantine in an extremely Christian light, building holy sites and allegedly destroying pagan temples. The majority of Constantine’s imperial letters appear in book 3.

Book 4 is largely concerned with Constantine and his personal life and final accomplishments, concluding with the death of Constantine. Most of the work is devoted to the illustration of Constantine’s personal piety. His trip to Persia is painted in an apologetic universal Christian theme, his laws forbidding idol worship of his own image and the reiteration of the suppressing of idol worship and sacrifice.[7] As the work concludes, Eusebius give much effort to uncover a personal Constantine, taking time to describe the Emperor as a remarkable public speaker and preacher, as well as a listener. Near the Emperor's death, Eusebius focuses on Constantine’s mental and spiritual strength, as well as his physical strength, helping finish the portrait of a nearly godlike man. The panegyric ends with the death of the Emperor, his funeral, and the succession of the throne.

Treatment of Constantine[edit]

Eusebius’ treatment of Constantine has generated much of the controversy surrounding the text. Eusebius’ use of the panegyric style results in an extremely generous treatment of Constantine that has been noted for its less than objective aims. Timothy Barnes notes that Eusebius clearly omits accounts and information to portray Constantine in the favorable light.[8] Eusebius advanced the idea of divine right on Constantine, as he was Emperor due to God’s will, and is God imitator on earth.[9] Eusebius’s narrative constructs Constantine as god-sent, in order to end the persecution of Christians under the Roman Empire, and ensure the correct worship of God. Eusebius’ vehicle for this narrative is metaphor, and he explicitly paints Constantine in the image of Moses.[10]


Eusebius's known sources for painting a textual portrait of Constantine and his rule come from eight legal texts, forty-six biblical references, and eight literary references.[11] Eusebius often referenced his own former works, forty-one times in Life of Constantine, most notably Ecclesiastical History (Historia Ecclesiastica) and the Tricennalian Oration (Laus Constantini). The Ecclessiastical History itself has many imperial documents and letters from Constantine, some repeating their appearance in Life of Constantine. Eusebius often quotes verbatim both his own work and the imperial documents; however, he also quotes without citing, often to help build his narrative of Constantine as a god-sent emperor.[12]


Skeptics hold that the marriage between the panegyric and bibliographical styles mixes legend with fact, making the text wholly unreliable. Indeed while many accept the work as generally reliable, few modern scholars claim that the text is not without its question marks, especially in regards to the motives and biases of Eusebius.[13] Eusebius consistently neglects relevant information to portray Constantine in a favorable light. He also engages in the politicization of several topics in the work, most notably the campaign against Licinius and the Council of Nicaea.[12] In the former case, Eusebius engages in the tarnishing of Licinius’ reputation, painting him a supporter of pagans and a truce breaker, both claims that are historically dubious.[14] Eusebius was himself a participating member of the Council of Nicaea and his motivations in writing on the matter in which he was an active participant must be approached with caution. Eusebius also takes great pain in describing himself as very close to the Emperor, when in fact, the opposite is most likely. Barnes notes that Eusebius and Constantine meeting in person was a rare occurrence, as Eusebius did not reside near the capital, nor did he have special access to Constantine, as he claims in Life of Constantine. Rather, Barnes claims that before the Council of Nicaea, Eusebius might have seen the Emperor once, in a large crowd of people. It wasn’t until 25 years later that Eusebius would meet the Emperor, at the Council of Nicaea. After the Council however, personal contact was sporadic at best. Even letter exchanges between the two were infrequent.[15] It is clear that Eusebius was not the courtier he had painted himself as in Life of Constantine.

Historical significance[edit]

Life of Constantine remains the most important work for examining the reign of Constantine.[16] Only a select amount of pagan accounts of the reign exist or have been discovered, with only one pagan panegyric known to exist. While Eusebius does have a clear pro-Christian bias, Life of Constantine also provides several insightful secular matters that have not been discovered outside of the work. However, despite its modern significance, Life of Constantine was widely obscure in the 4th and 5th centuries, and did not reach popularity until much later in history.[17]
