Editing Lactantius (section)

===Apologetics===
He wrote [[apologetic]] works explaining [[Christianity]] in terms that would be palatable to educated people who still practiced the [[religion in ancient Rome|traditional religions of the Empire]]. He defended Christian beliefs against the criticisms of [[Hellenistic philosophy|Hellenistic philosophers]]. His ''Divinae Institutiones'' ("Divine Institutes") were an early example of a systematic presentation of Christian thought.
*''De Opificio Dei'' ("On the Workmanship of God"), an apologetic work, written in 303 or 304 during Diocletian's persecution and dedicated to a former pupil, a rich Christian named Demetrianius. The apologetic principles underlying all the works of Lactantius are well set forth in this treatise.<ref name=Healy/>
*''[[Institutiones Divinae]]'' ("The Divine Institutes"), written between 303 and 311.<ref name=Healy/> This is the most important of the writings of Lactantius. It was "one of the first books printed in Italy and the first dated Italian imprint."<ref>{{cite book

}}</ref> As an apologetic treatise, it was intended to point out the futility of pagan beliefs and to establish the reasonableness and truth of Christianity as a response to pagan critics. It was also the first attempt at a systematic exposition of Christian [[theology]] in Latin and was planned on a scale sufficiently broad to silence all opponents.<ref>Lactantius ''The Divine Institutes'', translated by Mary Francis McDonald [[Catholic University of America Press]] (1964)</ref> [[Patrick Francis Healy|Patrick Healy]] argues that "The strengths and the weakness of Lactantius are nowhere better shown than in his work. The beauty of the style, the choice and aptness of the terminology, cannot hide the author's lack of grasp on Christian principles and his almost utter ignorance of Scripture."<ref name=Healy/> Included in this treatise is a quote from the nineteenth of the [[Odes of Solomon]], one of only two known texts of the Odes until the early twentieth century.<ref>Charlesworth, James Hamilton, ''The Odes of Solomon'',  Oxford: Oxford UP, 1973, pp. 1, 82</ref> However, his mockery of the idea of a [[Spherical Earth|round Earth]]<ref>

*''[[De mortibus persecutorum]]'' ("On the Deaths of the Persecutors") has an apologetic character but given Lactantius's presence at the court of Diocletian in Nicomedia and the court of Constantine in Gaul, it is considered a valuable primary source for the events it records. Lactantius describes the goal of the work as follows: <blockquote>"I relate all those things on the authority of well-informed persons, and I thought it proper to commit them to writing exactly as they happened, lest the memory of events so important should perish, and lest any future historian of the persecutors should corrupt the truth."<ref>Lactantius. [http://www.evolpub.com/CRE/CREseries.html#CRE14 ''On the Deaths of the Persecutors''], p. xix.</ref></blockquote> The point of the work is to describe the deaths of the persecutors of Christians before Lactantius ([[Nero]], [[Domitian]], [[Decius]], [[Valerian (emperor)|Valerian]], [[Aurelian]]) as well as those who were the contemporaries of Lactantius himself: Diocletian, [[Maximian]], [[Galerius]], [[Maximinus Daia|Maximinus]] and [[Maxentius]]. This work is taken as a chronicle of the last and greatest of the persecutions in spite of the moral point that each anecdote has been arranged to tell. Here, Lactantius preserves the story of [[Constantine I of the Roman Empire|Constantine's]] vision of the [[Chi Rho]] before his [[religious conversion|conversion]] to Christianity. The full text is found in only one manuscript, which bears the title ''Lucii Caecilii liber ad Donatum Confessorem de Mortibus Persecutorum''.<ref name=Healy/>
