1536: Sebastiano de Montecuccoli, poisoner of the heir?

On this date in 1536, Italian nobleman Sebastiano de Montecuccoli was torn apart at the Place de la Grenette in Lyons for poisoning the dauphin Francis, heir to the French throne.

Sebastiano de Montecuccoli was a knight from Ferrara who had arrived in France in the train of the Catherine de’ Medici when she was married off to the no. 2 French prince Henri. He was fast friends with the royal princes, but his proximity to the family horribly turned against him when the 18-year-old Francis played a game of tennis, then caught ill and dropped dead. The last thing poor Francis had done was ask Montecuccoli for a glass of water.

In an era of forensics-by-guesswork, a sudden and unexplained death inevitably drew suspicions of poison — all the more so in a France gone security bonkers in the wake of the Affair of the Placards.

So just was in that glass of “water,” eh?

Sebastiano, upon his arrest, was found to possess a tome of poisons. This was a common enough interest among his class. (Catherine de’ Medici also had an interest in poison.) Nevertheless, it was great material for tunnel-vision investigators, and the young Italian soon provided a corroborating self-incrimination under torture: Sebastiano had offed the crown prince on orders from France’s longtime rival Charles V, who also just happened to be fighting a war with France over the duchy of Milan at that very moment.

Sebastiano attempted to recant this confession once he was off the rack, but to no avail. Many 16th century contemporaries could descry the eventual consensus of posterity that Sebastiano was a naif, and not an assassin. (Francis likely died from a disease.) Less generous by far was the judgment of the Lyonnaise citizenry who fell upon and ravaged Sebastiano’s body after it had been torn apart by horses.

Thanks to the unexpected death of the heir that triggered this horrible punishment, Francis’s brother Henri advanced to the crown prince seat and eventually became Henri II of France (until Henri’s own unfortunate sporting mishap) … and that Italian bride Catherine de’ Medici became Queen of France.

On this day..
