[1] Mathurine is noted in the registers of the court with the position Plaisante,[2] which was the title of female jesters of the court in 16th-century France, of which there were evidently several, such as Mademoiselle Sevin, the jester of the queen of Navarre.
She was known for her extravagant costume as an Amazonian warrior, complete with shield, armor, and a wooden sword.
[5] Mathurine was a fervent Roman Catholic, and was said to employ her comical talent and wit to convert Huguenots back to Catholicism.
[2] She was present in 1594 when Henry IV was wounded by the assassin Jean Châtel, and arrested him herself: Mathurine it was who arrested the youth who attempted to assassinate Henri IV, on the 28th of December.
"Devil take that fool with her tricks," cried his Majesty… Mathurine sprang to the door, and barring the passage, prevented the escape of the King’s assailant.
