Jan van Kessel the Younger are attributed about 200 small still lifes produced in Southern Europe in the late 16th and early 17th century. Jan van Kessel the Younger's small known authentic oeuvre is different in style and execution and substantially higher in quality than the works, which have now been attributed to Pseudo Jan van Kessel the Younger. His portrait style was described by his contemporary Antonio Palomino as very close to that of his fellow Flemish painter Anthony van Dyck. Van Kessel was a specialist of the genre of group portraits. An example is the "Portrait of a family in a garden" in
Anthony van Dyck portrait tradition—of painters such as William Dobson, Robert Walker and Isaac Fuller—into what certainly became elegant blandness in the hands of many of van Dyck's successors, like Lely or Kneller. The conventional view has always been more favourable: "When Van Dyck came hither he brought Face-Painting to us; ever since which time ... England has excel'd all the World in that great Branch of the Art’ (Jonathan Richardson: "An Essay on the Theory of Painting", 1715, 41). Thomas Gainsborough is reported to have said on his deathbed "We are all going to heaven, and Van Dyck is of the Company."
