Inside the Saint-Nicolas church in Blois, I saw and took pictures of this statue, not really knowing if it was new, old, famous, or what. It turns out to be a 17th century work by an unknown artist. It's an example of the Madeleine repentante theme in Counter Reformation art. The 16th and 17th century Counter Reformation is also known as the Catholic Reformation or the Catholic Revival.
This Madeleine repentante ("penitent Mary-Magdelene") has recently been restored. According to an article I read in the local Nouvelle-République newspaper, the statue was in bad shape and in 2015 was sent to Tours for restoration by a specialist named Delphine Bienvenut. The restoration was supposed to take about six months and was, according to the newspaper, to be un simple lifting (just a facelift).
Instead, Delphine Bienvienut discovered traces of polychromatic paint on the stone statue. A different kind of restoration was required, and a six-month project stretched to four years. The Madeleine repentante has now been restored to its original pink-cheeked splendor. However, though the original statue was known to show Mary Magdalene holding a human skull in her left hand (another well-known theme), the whole left arm was determined to be un-restorable. The statue was given a new, more prominent placement in the église Saint-Nicolas when it was taken back to Blois in early April of 2019.
Happy Bastille Day!
