The signature and inscription on the reverse of this painting reveal the identity of the subject: “Josef Edler von Wertheimstein, painted in Klagenfurt, H. B. 1921.” The origins of Herbert Boeckl’s (1894–1966) impasto are still unclear. The Carinthian artist’s extremely pastose style of painting seems to be without precedent in both Viennese Modernism and the art of his contemporaries in Paris and Berlin. A link might be found to the oeuvre of Oskar Kokoschka (1886–1980), even though Boeckl was not interested in the splendor of color that marked Kokoschka’s works in these years. Instead, he virtually submerged the subject in Portrait of Josef von Wertheimstein both in the mass of colors and in the shades he selected.
