Anyone visiting the Louvre is bound to be drawn to all the painted, sculpted, carved and shaped faces. The images of men, women and children in their time and country, known or anonymous. Are they good likenesses? Is likeness what the art of portraiture strives to achieve? Did the people portrayed even exist? From King Gudea to Napoleon, Alexander the Great to Baldassare Castiglione, La Belle Nani to Monsieur Bertin, these thirty or so works from the Louvre give a simple history of the art of portraiture.
