|Venus and Mercury with Cupid|
Nicolas Chaperon (1612-1655)
Don Antonio and Antonio Neri were both born in 1576. It is widely assumed by historians that the prince contracted the disease in his late teens, as a soldier and diplomat fighting the Ottoman encroachment into Hungary in the 1590s. What is not widely known is that he was sexually active as early as age fifteen. Crossed out and marked "in error" is a curious entry in the Florentine baptism register. Lines dated 31 October 1592, All Hallows Eve, record a male child, also named Antonio, born to the Medici Prince of Capestrano by the widow Madonna Isabella Casini. The following year, he was given a military commission and shipped to the front.
During his service, he was plagued by illness; he did participate in several battles, but was then reassigned to diplomatic duty. Upon return to Florence, the prince was ill for most of the ensuing year, running a fever that lasted for many weeks, keeping him bedridden for the entire summer. Later in the year, he suffered what was described as a terrible attack of "arthritic pain," leaving him immobile. These symptoms later resolved into "horrible diabetes," causing paralysis of the left side. It is difficult to imagine that the severity of Don Antonio's illness would not garner the full attention of the medical staff associated with the royal household. The symptoms described above are all consistent with syphilis.
Antonio Neri's father, Neri Neri, was physician to the royal family and must have been involved to a greater or lesser extent in Don Antonio's treatment. Dr. Neri’s 1585 treatise on left-side paralysis indicates he was considered an expert on the matter. Furthermore, it is easy to imagine that the doctor's alchemist son, the same age as the prince, might take an interest. While it is very possible they were already acquainted, perhaps this period was an opportunity for a bond to cement between the two Antonios.
This infection, which the Italians referred to as the "French disease" and the French as the "Italian disease" was elsewhere attributed to the Spanish, Germans and the Polish. Current research is still undecided if Spanish explorers brought the bacterium back with them from South America. The first recorded epidemics of syphilis occurred soon after Christopher Columbus’ return to Europe in the late 1400s.
Calamine and mercury were both effective at closing the open ulcers that were associated with advanced syphilis. Hence the expression "A night with Venus and a lifetime with Mercury." While illness in the royal court was generally kept a closely guarded secret, Don Antonio did develop a very public reputation for spending lavish sums to acquire natural secrets and recipes. It would be foolish to deny that his medical condition played a role in his devotion to discovering new medicines and in his pursuit of the philosopher's stone, which according to legend could cure all disease.
In the first decade of the 1600s, while Antonio Neri was in Flanders, the prince's condition deteriorated. But as soon as Grand Duke Ferdinando was dead, a baby girl was born to Don Antonio's handmaid and then three boys to another woman he employed as a music teacher. While it would be easy to jump to conclusions about promiscuity, the evidence is that as each birth became known, the royal family mobilized to break-up Don Antonio's relationships. As the son of Grand Duke Francesco, and arguably the rightful heirs to the throne, Don Antonio's children were a vexing issue for his uncle's family, who currently enjoyed power.
As the second decade of the seventeenth century wore on, Don Antonio gave up horseback riding, and then travels all together. By 1620, he was confined to his bed. On 2 May 1621, he died at the age of forty-five. An account of his funeral procession tells that his lower body was so ravaged, that blankets were used to cover the carnage.
