Resumen de Rubens's Portrait of Isabella de Bourbon, Queen of Spain
The study from life in an English private collection which Rubens painted in the autumn of 1628 of Isabella de Bourbon, first wife of Philip IV of Spain, is here published, and the often doubted version in the Kunsthistorisches Museum, Vienna, is shown to be a copy post-1640. The significance of the Albertina drawing prepared by Pontius and used as a model for his 1632 engraving of Queen Isabella is examined afresh in view of this rediscovery and of misleading publication in the Corpus Rubenianum Ludwig Burchard.
