The way this video begins will make you think it's about Lucretia Borgia, but that's just setting the scene for the real story. Even if Borgia were guilty of all the crimes she's been accused of, she still wouldn't hold a candle to Giulia Tofana. Tofana made a good living manufacturing cosmetics, but her real talent went into her signature product, Aqua Tofana. It's a perfect product name that will stick with you because it's fun to say. Aqua. Tofana. While the concoction was officially a cosmetic, those in the know could use it to obtain an old-fashioned divorce... if you know what I mean. And if you don't, you should read the many posts we've shared about arsenic. In other words, Giulia Tofana was a 17th-century professional poisoner, and a prolific one, too. Weird History tells her story with a bit of snark, since that's the only way to make it palatable.
