Portrait of Marquise Lomellini, with her children at prayer

Van Dyck employed chiaroscuro to create depth and volume, focusing attention on the central figures. The predominantly muted color palette, including the Marquise's black attire and the children's white clothing, contributes to a somber, formal atmosphere.

Created during van Dyck's mature period, following his apprenticeship under Peter Paul Rubens and his admission as a master to the Guild of Saint Luke (1617), the painting is now part of the collection at the São Paulo Museum of Art.

This work exemplifies the Baroque period's emphasis on emotional intensity and the Flemish tradition of detailed, realistic portraiture, blending religious and secular themes.

As a characteristic example of van Dyck's portraiture, combining religious and aristocratic elements, the painting contributes to the artist's reputation for capturing the essence of his sitters within the cultural and religious climate of his time.
