326: Crispus and Fausta, incestuous lovers?

On an uncertain date perhaps around late July of 321,* the Roman emperor Constantine the Great had his son and also his wife mysteriously put to death.

It’s mysterious because besides execution, Constantine had a damnatio memoriae passed over his former family to bury any record of their sins in Time’s obscurity. These edicts didn’t always work … but in this case, if there were any who dared to record what happened, that illicit account did not survive its journey from antiquity.

But it was surely a shocking scandal in its time.

Crispus was Constantine’s first-born son and very much in the father’s favor. He was the child of a wife or concubine named Minervina. In 307, Constantine put this woman aside to make a more politically expedient marriage to Fausta, the daughter of Diocletian‘s retired-now-unretired co-emperor Maximian who with his son Maxentius held sway in Italy at that moment of the Roman Tetrarchy‘s ongoing collapse.**

Although Crispus didn’t offer his dad much in this situation by way of family alliances, Constantine kept him in his favor — by all appearances grooming him as an heir. Call it paying it forward: as a young man, Constantine himself had been in a similar position when his father Constantius dumped Constantine’s peasant mother in favor of an imperial marriage. That moment might have strangled a world-historic career before it even began, but Constantius instead chose to keep Constantine on the paternal cursus honorum.

So it went with Crispus — for a while.

In 317, Constantine, now emperor in the western part of the empire,† made Crispus into his Caesar; the boy ruled in Gaul and Germania for several years, thrashing barbarian tribes as he ought. Dad, meanwhile, was maneuvering towards victory over his eastern opposite number Licinius, with Crispus contributing an important naval victory in 324.

The young man (in his twenties at this time; his precise year of birth is uncertain) seemed on his way to a scintillating future.

Things went pear-shaped suddenly in 326 when his father had him executed without any kind of warning that survives in the scant records available to us — and not only Crispus, but also Constantine’s own wife, that Fausta whose marriage might have threatened the boy’s status.

We don’t know why but the rumor as trafficked by the much later Byzantine historian Zosimus suggests a possible Parisina and Ugo scenario: “He put to death his son Crispus, styled Caesar, on suspicion of debauching his mother-in-law Fausta, without any regard to the ties of nature … [and] causing a bath to be heated to an extraordinary degree, he shut up Fausta in it, and a short time after took her out dead.”

It is down to conjecture what one ought to make of this nth-hand scandal-mongering; for impugning someone’s character one can hardly do better than an incest accusation. The story does appear to fit the few available facts, however, and Fausta was much closer in age to Crispus than to Constantine. It might also be noteworthy that three of Fausta’s sons went on to become Emperor and one daughter Empress but none of them ever rehabilitated mom.

Damned memory be damned, Crispus was rediscovered during the Renaissance and favored with several dramatic renditions embellishing the young man as a tragic hero, often with speculation that he was wrongly condemned to Constantine’s everlasting shame.‡ The events surrounding Crispus’s death being almost entirely obscured, writers could really go nuts with it; for example, Sir Walter Scott‘s Count Robert of Paris (set in Constantinople during the Crusades) features the story of an entirely fictitious penance built into subsequent Byzantine execution rituals by a remorseful Constantine:

But the death-blow had no sooner struck the innocent youth, than his father obtained proof of the rashness with which he had acted. He had at this period been engaged in constructing the subterranean parts of the Blacquernal palace, which his remorse appointed to contain a record of his paternal grief and contrition. At the upper part of the staircase, called the Pit of Acheron, he caused to be constructed a large chamber, still called the Hall of Judgment, for the purpose of execution. A passage through an archway in the upper wall leads from the hall to the place of misery, where the axe, or other engine, is disposed for the execution of state prisoners of consequence. Over this archway was placed a species of marble altar, surmounted by an image of the unfortunate Crispus — the materials were gold, and it bore the memorable inscription, TO MY SON, WHOM I RASHLY CONDEMNED, AND TOO HASTILY EXECUTED. When constructing this passage, Constantine made a vow, that he himself and his posterity, being reigning Emperors, would stand beside the statue of Crispus, at the time when any individual of their family should be led to execution, and before they suffered him to pass from the Hall of Judgment to the Chamber of Death, that they should themselves be personally convinced of the truth of the charge under which he suffered.

* Approximate times around the spring and summer of 326 have been proposed by various authors based on the very vague allusions of ancient sources. This author argues that numismatic evidence permits a more precise triangulation. Constantine in 326 journeyed from his new capital in the east to Rome: an imperial mint traveled with him, striking coins as it went — and some of those coins show Crispus. His presence on coins from various stops of this journey indicates that Crispus must have been alive as the procession reached Rome on July 21, 326, but the Caesar vanishes from them, and from history, immediately thereafter.

** The History of Rome Podcast narrates this period, with Constantine’s rise into political relevance in episode 130.

† The Tetrarchy was still tetrarching along pending Constantine’s victory over all: the system featured separate senior emperors East and West each dignified Augustus, and each Augustus had a junior fellow-emperor and heir titled Caesar. Constantine was Augustus of the West, and Crispus was a Caesar.

‡ Fausta tends to get somewhat shorter shrift than her putative lover. Crispus’s presence in the literary culture would appear to make him the namesake of the Boston American Revolution martyr Crispus Attucks. African-descended men in North America often carried Roman names, though “Crispus” was by no means a common one.
