11. I will now state my reasons for writing this Work; some may think this labour of mine superfluous, especially as so many learned authors have written expressly and extensively the history of various heresies, as Tertullian, St. Iræneus, St. Epiphanius, St. Augustin, St. Vincent of Lerins, Socrates, Sozymen, St. Philastrius, Theodoret, Nicephorus, and many others, both in ancient and modern times.

I hive said in a small compass, but still, not with such brevity as some others have done, who barely give an outline of the facts, and leave the reader dissatisfied, and ignorant of many of the most important circumstances.
