One of the most important passages in "De Mortibus Persecutorum" occurs in Chapter XLIV wherein Lactantius describes the Battle of the Milvian Bridge and the theophany which Constantine experienced just prior to the battle. Differing from the account of Eusebius Pamphilus who specifically recounts a vision of a cross in the sky with the words, in hoc signo vinces, Lactantius describes a dream in which Constantine is instructed to paint the chi-rho on the shields of his soldiers.
