The seven books of the Diuinae institutiones ("The Divine Institutions")are the most important of the writings of the Christian author Lactantius. Their critical edition is continued here with a secondfascicle containing books III (with evidence for philosophical texts otherwise lost) and IV (with numerous quotes from the Bible). To this end the various manuscripts were collated, the constitution of the text checked on the basis of previous research, and the evidence for sources and subsequent textual transmission updated. The firstfascicle with books I and II was published in 2005.
