The Great Pox

illustration from Meyers Konversations-Lexikon 1897

Peculiar potions, potent plagues and powerful penicillin – syphilis inspired it all.

From 1493 onwards, everyone who was anyone caught syphilis. Ivan the Terrible, Henry VIII, Friedrich Nietzsche, Gauguin, Keats, Oscar Wilde, Beethoven, Manet and Al Capone all allegedly picked up the disease. Given that the ‘Great Pox’ was a known venereal disorder, it is no surprise Casanova also made the ever-growing list.1

What’s in a name

Not only did syphilis chalk up many famous names, it had numerous names itself. Many were based on the country or people blamed for spreading it. For instance, the English and Italians called it the ‘French disease’, whereas the French called it the ‘Spanish disease’.2 It wasn’t until 1530 that the name syphilis emerged thanks to Italian poet, mathematician and physician Girolamo Fracastoro’s Latin poem Syphilis. Apparently, Syphilis, a shepherd, offended Apollo, who took revenge by creating a hideous disease.1-3 

Origin stories

The source of Apollo’s curse has triggered arguments since it appeared in Western Europe in the late 15th century. Did Christopher Columbus bring the scourge from the New World to Spain in 1493? Was it a virulent variant of an Old World pestilence like yaws?1-5 The answer may be ‘a bit of both’. There is solid evidence that syphilis began its global spread when Charles VIII of France attacked Naples in 1494. Troops on both sides included Spanish mercenaries … and prostitutes. When the French retreated, as Voltaire wrote, ‘syphilis went with them’.

There is also support for a truly old Old World origin. Examination of skeletons suggests the ancestor of syphilis and Old World diseases like yaws and bejel spread from Africa through Asia to North America, where about 8 million years ago it evolved into syphilis.

A very nasty microbe

Like its disease cousins, syphilis is caused by Treponema – spiral-shaped bacteria called spirochetes. But each of the diseases has different symptoms. Bejel (Treponema pallidum endemicum) causes mouth sores and destructive bone lumps. Yaws (T. pallidum pertenue) causes skin sores and disfiguring growths on the legs, nose and mouth.7 And syphilis (T. pallidum) begins with genital sores, which heal, only to be followed by fever, rash, aches, bone pain at night and genital warts. The final phase consists of disfiguring abscesses, ulcers and debility, even madness or death.

Early treatments for syphilis were as outrageous as its symptoms: flayed pigeons and frogs applied to an infected penis, blood-letting and suffocating steam baths.2,4 The first elixir was a purgative made from guaiacum, a New World tree. It was ineffective, so mercury-based products dominated until the 20th century, despite dangerous and painful adverse effects.2-4,9-11

Syphilis became less virulent over time, but the first ‘cure’ wasn’t developed until after T. pallidum was discovered in 1909. While the ultimate cure was the advent of penicillin in 1943, the reasonably effective drug, Salvarsan, was available by 1910.1-3,9
Adding to Salvarsan’s glory was its status as the world’s first ‘magic bullet’, a treatment created in the lab targeting a specific agent.
