Charles Le Brun's iconic drawing of the Marquise de Brinvilliers on the way to her execution in July, 1676 portrays her as a terrified, downtrodden creature, but the stories behind the portrait paint a very different picture of the woman whose crimes triggered the infamous Affair of the Poisons that infiltrated the court of Versailles and threatened to bring down the monarchy of Louis XIV. This article tells those stories.
