[]The exact dating of thedies imperii of Maximianus Herculius is a matter of scholarly contention. For example, while the authors of the PLRE date Herculius' Caesarship to 285/6 and his elevation to the rank of Augustus to March 286 (1.574), Barnes dates the Caesarship to July 285 and the elevation to Augustus to April of the next year(New Empire, 4, nn. 5-6). For a discussion of the present state of the debate, see Kienast(Dietmar Kienast, Römische Kaisertabelle, [Darmstadt, 1990], 268ff).

[]The "Great Persecution" is discussed by Barnes, Constantine and Eusebius, 17ff, Wm Ensslin, RE 7, s.v. "Valerius (Diocletianus) (142)," col.2484.47ff, and B.J. Kidd, A History of the Church to A.D. 461,(Oxford, 1922), 1.515ff

[]The rise of Maxentius and Maximianus' return to power are discussed by Barnes, Constantine and Eusebius, 30ff, E Groag, RE 14, s.v.

[]Elsewhere I and Arnold have have written. " For a discussion of the various theories about Maximianus' plots against Constantine I, see W. Huss, "Das Ende des Maximianus," in Latomus, 37(1978), pp. 719ff; the best introduction to the sources which treat Herculius' last days remains Moreau's commentary on Lactantius De mortibus persecutorum(J Moreau [ed.], De la mort des persécuteurs, Paris, 1954, II, pp. 366ff.)." (Michael DiMaio and Duane Arnold, "Per Vim, Per Caedem, Per Bellum: A Study of Murder and Ecclesiastical Politics in the Year 337 A.D.," Byzantion, 62, 175, n.113)
One question crossed this author's mind while compiling this essay about Maximianus. Why did Herculius put himself through all of this at the end of his career when it was obvious to everyone that he was not wanted? The best answer was provided by Harold Mattingly and B.H. Warmington who have noted that Maximian was "...[U]neducated and rather stupid."(OCD,2 s.v. "Maximian," 657).
