The Master's identity was established after an inscription was found on the reverse of a damaged painting, Christ with Crown of Thorns (1494) in the Royal Museums of Fine Arts of Belgium, Brussels, identifying the artist as Jean Hey, teutonicus and pictor egregius ("the famous painter"), and identifying the patron as Jean Cueillette, who  was secretary to the King and an associate of the Bourbon family. Stylistic similarities link this painting to the works attributed to the Master of Moulins.
