manuscripts at paltry prices to finance his migration to Vienna. The reasons for Vivaldi's departure from Venice are unclear, but it seems likely that, after the success of his meeting with Emperor Charles VI, he wished to take up the position of a composer in the imperial court. On his way to Vienna, Vivaldi may have stopped in Graz to see Anna Girò. Death Vivaldi moved to Vienna probably to stage operas, especially as he took up residence near the Kärntnertortheater. Shortly after his arrival in Vienna, Charles VI died, which left the composer without any royal protection or a steady source of income. Soon afterwards, Vivaldi became impoverished and died during the night of 27/28 July 1741, aged 63, of "internal infection", in a house owned by the widow of a Viennese saddlemaker. On 28 July, Vivaldi was buried in a simple grave in a burial ground that was owned by the public hospital fund. His funeral took place at St. Stephen's Cathedral. Contrary to popular legend, the young Joseph Haydn who was in the cathedral choir at the time had nothing to do with his burial, since no music was performed on that occasion. The cost of his funeral with a 'Kleingeläut' was 19 Gulden 45 Kreuzer which was rather expensive for the lowest class of peal of bells. Vivaldi was buried next to the Karlskirche, a baroque church in an area which is now part of the site of the TU Wien university. The house where he lived in Vienna has since been destroyed; the Hotel Sacher is built on part of the site. Memorial plaques have been placed at both locations, as well as a Vivaldi "star" in the Viennese Musikmeile and a monument at the Rooseveltplatz. Only two, possibly three, original portraits of Vivaldi are known to survive: an engraving, an ink sketch and an oil painting. The engraving, which was the basis of several copies produced later by other artists, was made in 1725 by François Morellon de La Cave for the first edition of Il cimento dell'armonia e dell'inventione, and shows Vivaldi holding a sheet of music. The ink sketch, a caricature, was done by Ghezzi in 1723 and shows Vivaldi's head and shoulders in profile. It exists in two versions: a first jotting kept at the Vatican Library, and a much lesser-known, slightly more detailed copy recently discovered in Moscow. The oil
