Career
She is best remembered for her association with the composer George Frideric Handel, for whom she sang both in Italy and in London. Vanini was born in Bologna. As well as singing for Handel, she also sang in operas by Alessandro Scarlatti and Giovanni Bononcini.
Her two Handel roles were those of Otho in Agrippina and Goffredo in Rinaldo.
These roles utilise only a limited range and tessitura. After Rinaldo her voice began to decline, but earlier Giuseppe Felice Tosi had praised her for her ability to introduce "Graces without transgressing against Time".
She died in Venice.
