Exhibited: Jerusalem, The Israel Museum, on loan 2010–2020. Note: Presumably painted in the late 17th or early 18th century, the present work is a copy after the double portrait by Martin Lambert, at Versailles (inv.MV 5885), painted as a presentation piece ('morceau de réception') for the Paris Académie, in 1675. Lambert was a pupil of Henri Beaubrun (1603-77), who is depicted here with his cousin, another portraitist, Charles Beaubrun (1604-92). The early French art historian, André Félibien (1619-95), recorded that the cousins would work alternately on a single portrait using the same palette, as is depicted here. The portrait they are working on is presumed to be that of Queen Marie Thérèse of France (1638-83); it is shown in the early stages of execution, an outline drawing traced in white on a dark ground. Other recorded copies of the unusual composition are those by Elisa Anfray, 1849, and Héléna Darmesteter, 1892.Please refer to department for condition report
