The individuals in the painting lived in the Flemish city of Ghant, in the southern Lower Countries, part of the Spanish Empire. They wore black clothing, highly valued in a region that produced dyed woolen cloth. Jean-Baptiste was part of the Flemish Council; the letter he holds in his hand proves his royal ties. His wife, Marie-Anne Nieulant, born in 1625 and married in 1653, is accompanied by their son, Jean-Baptiste, who wears a hat with a turned-down brim with a quilted front band that was used to protect the heads of children who were beginning to walk.
