It is generally agreed by art historians that the features of the Madonna are those of Agnès Sorel. She was a favourite mistress of Charles VII and bore him three daughters. She was known by the nickname, Dame de beauté. In 1450, Charles was away on a campaign at Jumièges. Agnès Sorel was at her home in Chinon, which the king had provided for her, but she wanted to be with Charles to give him some moral support. Despite being pregnant with their fourth child and it being a cold mid-winter day, she journeyed from her residence to join Charles at the village of Le Mesnil-sous-Jumièges. It was here that she suddenly became ill and died at the age of 28. While the cause of death was originally thought to be dysentery, in 2005 French forensic scientist Philippe Charlier examined her remains and determined that the cause of death was mercury poisoning, but offered no opinion about whether she was murdered. Agnès Sorel held great influence over the king and many historians believe that this made her many enemies, including the king’s son, the future king, Louis XI, and it could well be that she had been deliberately poisoned by her enemies. However this theory does not receive unanimous agreement as historians point out that, at that time, mercury was sometimes used in cosmetic preparations or to treat worms and that might have brought about her death.
