The “Portrait of Adele Bloch-Bauer” was painted in what has been called Klimt’s “Golden Style,” and indeed, it shimmers with golden particles. In 1903 the painter was in Ravenna and was greatly impressed by the powerful mosaic of the Empress Theodora in the nave of San Vitale. He sought to achieve similar splendor in his paintings of the period, such as his masterpiece “The Kiss” (1907–08). In the portrait of Adele, he worked with meticulous craftsmanship, painting the layers of pigments and laying on the gold leaf.
