The Belvedere Museum in Vienna (Austria) pays attention to Prince Eugene of Savoy (1663-1736). From Italian descent and a native French, he became one of the most influential Austrians who had a long-lasting impact on the country’s fate and its art and cultural history. As a diplomat and counsel to the emperors Leopold I, Joseph I, and Charles VI, he travelled across Europe from one theatre of war to the next, playing a decisive role in determining the future of the House of Habsburg. Throughout his lifetime, he devoted himself to the compilation of a comprehensive collection of paintings, copper engravings, incunabula, illuminated manuscripts, and books, which he displayed in his Viennese palaces. From ever changing war sites, Prince Eugene corresponded with artists and artisans, landscape designers and architects, as well as the most influential thinkers of his time. His acquisitions went down in the annals of European art and cultural history and facilitated the transfer of works of art from the court of the French king Louis XIV to Vienna.
