After finishing Dante’s Monarchia, I decided to look for some of the various commentaries and related works that editor Prue Shaw referred to in my Cambridge University Press edition. Several of these aren’t easily available, at least not in English, but I did find The Monarchia Controversy, edited by Anthony Cassell and published by the Catholic University of America Press. This includes Monarchia, Guido Vernani’s Refutation of the “Monarchia” Composed by Dante, and Pope John XXII’s bull Si fratrum, as well as Cassell’s own introduction and annotations.
Starting from the end of the book, Si fratrum is the document that sparked the controversy around the relationship between the papacy and the Holy Roman Emperor and whether one was subordinate to the other, though this controversy had been brewing for many years. It’s nice to have, then, for historical interest, but at only four pages it doesn’t develop any arguments, but simply proclaims that the pope is the legitimate ruler of the Empire when the office of emperor is vacant, and that it is his prerogative to approve of the election of the next emperor.
Guido Vernani’s Refutation is also relatively short, under thirty pages, and of mixed quality. Some of his arguments are disingenuous, as Cassell points out fairly often in his introduction and annotations. Also, while Dante kept a neutral tone throughout most of his work and portrayed himself as almost a third-party to the disputes, Vernani is sometimes outright abusive. Before introducing one of his last arguments, for example, he writes, “Here the wretch [Dante] reached the heights of his delirium: as he raised his mouth to heaven, his tongue lolled along the ground.” There’s nothing wrong with a polemical tone, and Dante isn’t subtle in calling some of his opponents sons of Satan, but in works dealing mostly in formal logic, theology, and history, this sort of attack stands out as mean-spirited and unworthy of formal debate.
That said, Vernani does raise some valid points. For example, he argues, quite reasonably, that only Christ could realistically have all of the virtues that Dante attributes to his vision of the universal monarch. He also points out that Dante’s interpretation of Roman history, with its heroism, nobility, and miracles, is very different from one of Dante’s own sources, St. Augustine, as well as several other authorities, who portray these same events in a very negative light.
I only skimmed through the Monarchia itself, but it seems readable enough. Of course, I’m not competent to judge the accuracy of one translation over another.
Over half the book is composed of Cassell’s annotations and his 100-page introduction, which is about three times longer than Prue Shaw’s in the CUP edition. Whether it’s three times more valuable depends on how much depth you want; both give an outline and some historical context, but Cassell goes into much more depth, especially on the reaction to Dante’s work, which Shaw only briefly mentions, and in analysing the method and substance of both Dante’s and Vernani’s arguments. This is all interesting to students of Medieval or philosophical history, but much of it isn’t really necessary to understanding either author. The annotations, which unfortunately are endnotes rather than footnotes, are also more thorough in Cassell’s edition, though not by a wide margin.
Now, I highly recommend reading Dante’s Monarchia, but which edition to read depends largely on what you’re interested in getting. If you just want the Monarchia itself with just enough additional explanation to understand the context and have a starting point for further study, then Shaw’s is perfect. If you’re interested in Medieval intellectual history and would like something more thorough, then Cassell’s is worth the extra cost – it’s fairly expensive new (over $70), but finding used copies isn’t difficult.
