The Poison Sold As A Woman's Cosmetic Oil

In 17th‑century Italy, a woman married to a violent man had almost no way out. Divorce was for wealthy men only. A wife was the property of her husband, her father, or her confessor. If the man beat her, or worse, she was expected to endure it until one of them died. And usually, it was her.

So in the backstreets of Rome, a quiet business grew up to even the odds — run by women, for women. Its most famous product was a poison called Aqua Tofana.

The horror Its genius was disguise. Aqua Tofana was a clear, tasteless, arsenic‑based liquid, sold in innocent‑looking bottles labelled as cosmetic oil or as “Manna of St Nicholas of Bari” — a popular healing remedy. On a woman’s dressing table, beside perfume and face creams, it looked like nothing at all. A husband would never suspect that the little vial of “makeup” was his death sentence.

And it killed slowly, which was the whole point. A few drops in food or wine, added over several days. The first doses brought on what looked like a common cold. Then came aches and stomach cramps. Then vomiting, dehydration, a burning in the throat and gut — the picture of a wasting natural illness. By the final drops, the man was dead in his bed.

To the doctor, it was disease. To the priest called to give last rites, it was God’s will. The husband, convinced he was simply dying, would put his affairs in order and leave everything to his devoted, grieving wife. She wept at the funeral. Then she was free. The poison gave abused women the one exit the law refused them — and it left almost no trace.

The trade was passed down through women. A poisoner remembered as Giulia Tofana is credited with perfecting and naming it in Sicily; when she died, she left the business to her stepdaughter, an astrologer and poison‑maker named Gironima Spana, who ran the network in Rome. Because apothecaries would not sell arsenic to women, they even recruited a renegade priest to buy the raw poison for them.

The modern relic It unravelled in 1659. By most accounts, a frightened client confessed — either to a priest or to officials — that she had poisoned, or planned to poison, her husband, and named her supplier. The Pope’s government launched a sweeping investigation now known as the Spana Prosecution, dragging in more than forty people, including noblewomen who had quietly made themselves widows.

On 5th July 1659, five women at the heart of the ring — Gironima Spana among them — were hanged in public in Rome. Dozens of their clients were imprisoned, flogged, or banished; some aristocratic women escaped by swearing they never knew their “cosmetics” were anything else.

Two relics survive. The first is the disguise itself: the poison was sold as “Manna of St Nicholas of Bari,” and the real Manna of St Nicholas is genuine — a fluid still collected from the saint’s bones in a church in Bari, Italy, to this day. Killers hid their poison behind the name of a real, still‑venerated holy relic.

The second relic is the name. Aqua Tofana never truly died. It became a byword for any slow, undetectable poison, feared for centuries. When Mozart lay dying in 1791 — more than a hundred years later — he became convinced someone had poisoned him with Aqua Tofana, and whispered the name in terror. He almost certainly had not been; but the legend alone was still strong enough, after all that time, to frighten a dying man.
