The date of the Divine Institutions of Lactantius has been accurately discussed, difficulties have been started, solutions proposed, and an expedient imagined of two original editions — the former published during the persecutions of Diocletian, the latter under that of Licinius. See Dufresnoy, Praefat. p. v. Tillemont, Mem. Ecclesiast. tom. vi. p. 465-470. Lardner's Credibility, part ii. vol. vii. p. 78-86. For my own part, I am almost convinced that Lactantius dedicated his Institutions to the sovereign of Gaul, at a time when Galerius, Maximin, and even Licinius, persecuted the Christians; that is, between the years 306 and 311.
