On this date in 1548, Giulio Cybo was beheaded in Genoa for plotting against his father-in-law Andrea Doria.
Successful though their line might prove, theirs was a house divided and the parents’ rivalry for precedence in their territory transferred to their two sons. Thus Giulio, the father’s favorite, makes his first appearance on history’s stage invading Massa with a cohort of gendarmes to seize power from his own mother.
The success of his rude maneuver was short-lived and mom soon restored her authority — backed by the imperial forces haunting the land during the interminable Italian Wars. Although Giulio was married to the daughter of the Genoese admiral Andrea Doria,* whose word was law in that city, the in-laws frustratingly stiffed him out of the dowry payment that Giulio intended to use to restore his Freudian conquest.
These material grievances, and a young man’s wide streak of tragic impetuousity,** drove Giulio into the arms of Giovanni Luigi Fieschi. The latter was a Genoese nobleman whose dramatic plot to topple Doria failed with operatic† absurdity in 1547 when Fieschi mid-coup fell off a gangway and drowned in the harbor. Only in Genoa.
Cybo’s complicity in this scheme could not be proven because he arrived too late to do anything other than make a politic show of support for the already-victorious Doria. But now, encouraged by the French — the Habsburg empire’s enemy in the aforementioned Italian Wars and therefore the sponsor of its every rival faction — Cybo gathered some fellow malcontents in Venice and began working up a plot to oust Doria, restore the liberty of Genoa, and really put all the parents in their place. Once bitten, however, the wily old Doria was on the lookout for these troublemakers and had Cybo’s circle infiltrated early. The young man was arrested en route back to Genoa to implement his design.
The letters of the Fieschi [family] which were found on his person left no room to doubt his guilt. Some tell us that he was several times tortured and confessed that Farnese, Maffei, Ghisa and the Pope himself were accomplices in the plot, and that the Fieschi and Farnese were its instigators.
The emperor did not wish to execute Cybo; and we find evidence in documents of the period that even the bloodthirsty Gonzaga made every exertion to save him. On the other hand Graneville and Doria laboured with all their power to secure his punishment. In fact, so soon as Doria heard of this plot, committed rather in intention than act and excusable by the youth of the conspirator, “the prince (I use the words of Porzio) inflamed to wrath by the offence and full of vengeful animosity, disregarded the double tie which bound him to the young man, and made incessant appeals to Caesar for the blood of his relative.”
Many Italian and foreign princes asked grace for the prisoner, and the emperor was at first undecided; but severity triumphed over mercy — Doria desired vengeance and he obtained it. The victim met his fate with manly intrepidity. He was beheaded and his body exposed between two wax candles in the public square … on the 18th of May, 1548. He was scarcely twenty years of age.
Porzio says: —
His courage and military capacity inspired all who knew him with the conviction that, if he had not perished in boyhood, he would have become one of the first captains of his age. He made a single mistake: that of endeavouring to expel one foreigner with another — to drive out the Spaniards in order to establish the French in Italy.
* This man, one of the great naval captains of his age, was of course the namesake of the Genoese ocean liner Andrea Doria that sank in 1956.
** Cybo “liked not to rest contented in the battle of life,” was James Bent’s judgment, although it is difficult to tell that he ever had the option to do so.
** Well, stage-worthy at any rate: Fieschi’s fiasco is the basis of Schiller’s play Fiesco.
