Tronie

A tronie (from the Dutch for "face" or "mug") is a small-scale study of a head or bust, painted not as a commissioned portrait but as an exploration of expression, character type, or costume. Popular in the seventeenth-century Dutch and Flemish Golden Age, tronies typically depict anonymous, often exoticised sitters — an old man, a soldier, a girl in an oriental turban — rather than identifiable patrons. Vermeer's Girl with a Pearl Earring is the most celebrated example: her fanciful turban and single pearl mark her as a type rather than a named individual, which is precisely why the painting has been nicknamed the "Mona Lisa of the North" — an idealised face inviting endless projection rather than a documented likeness.
