12 years span 14 original productions (including premieres). i.e. 14 roles written by Vivaldi specifically for Anna. 2. From their first show together to their last: 15 years span 22 productions (including revivals and revised versions) 3. Their collaboration represents 15 years out of: 21 years (Anna). (length of her career whilst Vivaldi was alive) 18 years (Vivaldi) (length of his opera career whilst Anna was active professionally) 4. Their partnership lasted until the very death of the composer in 1741, or very close to it. This sort of long and fruitful professional collaboration is unheard of concerning Vivaldi. And generally speaking, it was rather uncommon. For instance, Senesino, whom we consider as closely associated with George Frideric Handel for the many famous operas they collaborated on, spent 13 years working with Handel, out of 33 years (length of his career whilst Handel was alive). Together they created 16 roles and collaborated on 3 revivals. Finally, they stopped their partnership 7 years before the death of the composer. Private life Without a patron With the exception of Alderano Cybo-Malaspina, Duke of Massa and Carrara (who in 1725, through Vivaldi, gave her money for the purchase of a harpsichord), she seems to have always worked without depending on patrons. (Alderano dissipated the assets and heritage accumulated by the Cybo dynasty, including the Duchy of Massa and Carrara itself.) Last journey with Vivaldi In 1741, on his way to Vienna where he wished to take up the position of a composer in the imperial court, Vivaldi may have stopped in Graz to see Anna Girò, and she likely went with him on his journey. Her schedule seems to support this theory as the records show that she was in Graz in 1740 and 1741 and then in Vienna in 1742. Vivaldi was hoping to make a fresh start in Vienna. However his asthma, exhaustion and the death of the music-loving Emperor Charles VI, one of his great admirers, put an end to the project before it had even begun, and the composer died on 28 July of the same year at the age of 63. A secret wedding In 1748, while on tour in Piacenza, Anna met Count Antonio Maria Zanardi Landi, a local nobleman. He followed her back to Venice and persuaded her to marry him, despite the disparity of their conditions. They married in secret on 20 July 1748 in
