Lactantius

Lucius Caecilius Firmianus Lactantius (c. 250 – c. 325) was an early Christian author and apologist, often called the 'Christian Cicero' for his exceptional Latin prose style. He served as a rhetoric professor in Nicomedia under Emperor Diocletian, later converted to Christianity, and became an advisor to Emperor Constantine I and tutor to his son Crispus. His most important work is the *Divinae Institutiones* (The Divine Institutes), a systematic apologetic treatise defending the reasonableness of Christianity to pagan critics[1][2][7].
