Guy de la Fontaine

Guy de la Fontaine arrived in Alexandria in 1564 on what was, at its core, a quality-control mission. As physician to the King of Navarre, he had spent years prescribing mumia — the powdered remains of Egyptian mummies — to European patients who believed it cured everything from epilepsy to bruising to internal hemorrhage. The trade was enormous, the prices ruinous, and de la Fontaine, to his credit, wanted to know what he was actually giving people.

What he found in Alexandria should have collapsed the entire industry. A local merchant, apparently unbothered by the presence of a royal physician, walked him through the back-room operation without hesitation: freshly executed criminals, recently deceased slaves, anyone whose body could be obtained cheaply and without ceremony. The corpses were dried in heat, packed into casks, and shipped north to European apothecaries who would sell them as the authentic remains of ancient Egyptians — charging accordingly. The merchant had around thirty bodies in inventory when de la Fontaine visited. He seemed proud of the throughput.

De la Fontaine published what he'd witnessed. He named the merchant. He described the process in clinical, damning detail in his 1564 account, making the case that the mumia flooding European medicine cabinets was not ancient, not Egyptian, and almost certainly not therapeutic. The response from the European medical establishment was, essentially, a shrug. Physicians kept prescribing it. Apothecaries kept stocking it. The market kept growing. The demand for mummy as medicine wouldn't seriously decline for another hundred years, despite de la Fontaine having provided, in the sixteenth century, a firsthand account of industrial-scale fraud.

What makes de la Fontaine remarkable isn't that he blew the whistle — it's that he did so clearly, specifically, and early, and the world simply didn't care. He isn't remembered as the man who exposed one of medicine's longest-running cons. He's remembered, to the limited extent he's remembered at all, as a footnote in the history of a practice he tried to discredit.
