Jean Mosnier was a French painter who trained with his father, a glass painter. A native of Blois, Mosnier was there when Marie de' Medici was in exile, and she commissioned works from him. She was pleased with his talent, and paid to have him go to Italy to further develop as an artist. In Italy, he studied with Cristofano Allori, Lodovico Cigoli and Domenico Passignano, and was inspired by painters such as Raphael. As a result, his works had an Italian influence.
Upon his return from Italy, Marie de' Medici continued to commission him. He soon became one of the most celebrated artists of the region, receiving further commissions from patrons in Tours, Chinon, and Chartres.
