Circle of Jan Jansz. Mostaert

'Circle of Jan Jansz. Mostaert' refers to works produced by artists closely associated with or directly influenced by the Dutch painter Jan Jansz. Mostaert (c. 1475, 1555/56), a court painter known for his refined portraiture and religious compositions in the Early Netherlandish tradition. These works share stylistic and technical characteristics with Mostaert's authenticated output but cannot be definitively attributed to his hand alone. Such designations are commonly used by auction houses and scholars to group paintings from his workshop, followers, or contemporaries working in his manner.
